Can you feed eggshells to hens? Well I can think of only one reason why not; they may turn to eating their own. It apparently does happen occasionally though we have not had much of a problem.

So how do you stop your hens from enjoying a fresh egg for breakfast every day? Our method seems to be working, and it is fairly simple; others make quite a meal of it.
One thing is certain. Your laying hens need a lot of calcium; at least the amount in an eggshell every day, plus for their own bones and nutrition.
Just like humans, a chicken starved of calcium will
not thrive. Have you heard of rickets? It's a serious disease caused by a deficiency of either the mineral or vitamin D. Luckily none of our free-range hens seem to have the
slightest desire to become couch potatoes; they get weak bones even if they get enough of both.
Too little exercise is the chief cause of osteoporosis in humans, rather than too little of the mineral from their food; and smoking too.
Whilst we are on the subject, did you know that humans who take supplementary calcium are more prone to heart disease? Any excess, not taken up because you are not walking enough, is deposited in the intima, the inner lining of the coronary arteries, and presumably others, causing high blood-pressure.
But that does not happen if you get too much calcium from the food you are enjoying.
But that is not going to happen to our chickens; with the amount of calcium going into an egg a day, there's not much likelihood of an excess from their food.
The laying mash that we purchase of course is an extra source of calcium for our hens, but we are trying to become self-sufficient, and our chickens with us.
Can you feed eggshells to hens? Yes, of course, you can, but it needs to be presented in a way that it has no resemblance to their produce.
Or they may want their egg, and eat it, same as we mistakenly enjoy cake; for them never and for us on high and holy days only. Or, we will both end up with an early demise.
Ours is a very simple process; first wash the eggshells, dry them in the sun to sterilise them, and then crush the lot with your fingers.
First the washing process should remove most of the egg-white, or any yolk that is stuck to the shell.
You do not want them to recognise those shells from the odour of an egg and I can assure you their eyesight and sense of smell is very keen.
It is not done rigorously. We just toss them into a bucket with water, swish it round a few times, rinse again perhaps, and then put them out in the midday sun.
By mashing them down a bit, they take up less space in the bucket and do not collect water when you are trying to dry them. Or, alternatively, place them shell side up in the sun. That is what I am doing now; almost anything goes.
The strong sunlight makes the eggshells more brittle, and will help to kill off any salmonella that may be lurking; it is a nasty bug.
Out comes an empty plastic honey bottle and within thirty seconds you have your crushed egg-shells. Nothing really could be easier, though it is one more chore to think about.
Actually, I sometimes toss them into the blender for about fifteen seconds, and the resultant crush is so fine that I just add it to their regular feed; we have had little problem with hens eating their own eggs.

Here are the back issues.
If your hens are confined, then you have to put the crushed eggs into the run. Originally I would not add it to their regular feed, but in a second eggshell feeder; just any old container. Now I am a lot more laissez-faire about the whole exercise; keep it simple.
Our hens range freely in a garden divided into five camps; one is where the boss grows her seedlings, and the hens are never allowed to set foot therein obviously. The other four have compost-heaps, so that is where I dump the shells.
Since the hens are rummaging most of the day around in the compost-heaps looking for worms and other tiny creatures, they soon find the eggshells. And make no mistake, they know what is good for them.
So, in our case, there is not the slightest connection between the nesting boxes, the food they get in the run, and the shells; we have had little problem with hens tucking into their own eggs.
Every now and again, an eggshell has obviously had a peck, but no damage is done.
In total, perhaps it is five-minutes work, twice a week; not too onerous.
Dry them in the sun, now just by tossing them on the grass.
I crushed these with a plastic honey bottle; actually they hardly ever go into the blender; that is too much PT.
Fairly regularly I go back to crushing them in one plastic container, using another.
Happy hens take a mud bath regularly!
No one was more astonished than I when I opened the roost this morning to find an impatient hen had laid her egg and it had dropped more than two feet without breaking. Can you feed the shells to your birds and is it effective? Without a doubt!
Previously before feeding our eggshells to our hens this was the result.
I now cover this tray with compost. It makes cleaning it a lot easier.
Prior to this the eggshells went straight into the compost heap which was fine unless the egg had been boiled. Cooked, they do not seem to decay. Then for a period they went along with all the other kitchen slops into the wonder of worm farms.
These are best chicken feed; a wonderful source of protein for them.
Becoming self-sufficient has been one of the most satisfying things I have ever strived to achieve. We have succeeded with our solar powered generator, and rainwater harvesting, free-range cage free eggs, fruit and vegetables.
Making the birds self-sufficient has meant fussing with can you feed eggshells to hens, growing corn for them, and of course the worm farms for protein.
This year we will have a huge crop of broad beans; they are the best vegetable source of protein at 25%; we just have to figure out how to make them palatable to the hens. Luckily they leave the plants alone. If you have worked out a way, please email me at contact.
How to plant broad beans has been a big step forward for us; they are simple legumes to grow compared to chickpeas and lentils, and we are hoping they make great chicken food.
Finding a protein source where they will not also decimate the plant, like ordinary green beans and peas, has been a mission.
The hens absolute favourite food after the worms is our stale 100% wholemeal bread. We add a vegetable protein in the form of our homemade authentic hummus recipe to lower the GI, and the hens behave as though it is Thanksgiving!
Unrefined wheat has a lot of betaine which they need; so do we.
What is betaine you may be asking?
You can choose a chicken tractor design; each has its strengths and weaknesses. Our hens range freely, but periodically have to be confined to quarters; then can you feed the shells to hens? Will they start eating their eggs?
Initially we only fed the hens eggshells by tossing them into the compost heap. I have heard of folk having to get rid of the whole flock because they started eating their own eggs. But now that they have been through the blender, they just go in with their feed; and they eat the lot.
But this confining of the flock to our chicken tractor design is really only a short lived thing; soon they are out and about once the seedlings have settled in. Mark I was too heavy to move about freely.
Can you feed eggshells to hens? In three years we have had little difficulties.
From Longbourne farm you have another slant on feeding eggshells to chickens.

Can you feed eggshells to hens came up when we had a few laid with no proper covering. They like all females including humans have a prodigious need for calcium.
