Feeding hens their own shells...

I have always feed them egg shells.....to me it's like giving back....I've had poultry for 30+ years and None have ever turned   mad or eaten their own eggs. ~Charm1704

One difference, perhaps, is that the chicken is pre-programed to gobble up any egg that breaks or is soft shelled, etc.  Sometimes this goes a wry and one fights egg eating hens, but it isn't a huge problem.  But I've never seen a chicken pass up a broken egg in the nest.  Whereas a cow wouldn't eat cow brains if she came across them.  Those had to be "hidden" within the feed.   Just an observation.

That tells me that "re-cycling" is part of the chicken's instinct and thus, completely natural and normal.  I absolutely feed back shells.

Someone once wrote:
 

If you have a pen of cows or horses that are starving and one dies...  The horses or cows would never ever start to eat the one that died.  The only way a cow or horse will eat cow or horse is if it is disguised and they are tricked into eating it.  This just goes against nature.

Now chickens.... they are scavengers.  If you just hold still too long in a chicken coop they will eat you. lol! ok maybe I made that part up.

I like this one  "if you faint in the chicken coop make sure you fall face first...cuz eyes are shiny."  

That one cracks me up!

I dry out the egg shells first.  Just a minute or two in the broiler on a cookie sheet, then I crush them all up so the girls don't get the idea that their eggs are yummy.

My chickens don't have any diseases to start with. And as stated, it's in their nature, it's biological for them. Chickens are oppertunistic cannibals, where cows can't cannibalize. Makes sense to me.

Since studies have shown that chickens have no brain tissue and are basically spineless(hence the derogatory term of "chicken") it would be somewhat difficult for them to get Mad Chicken disease due to the difficulty in keeping the disease alive in their bodies. 

As for the egg?  A chicken will gladly eat their own feces and anyone else's~including yours if given a chance~ and declare it "feather lickin' good" so I'm not a bit worried about an egg that has issued from the more sterile recesses of their reproductive organs.

Nope...not worried.  I don't bake them or sterilize them or spritz them with bleach before feeding them back to my chickens. 

I can usually spot sarcasm a mile away, but Beekissed, are you being sarcastic about chickens having no brain tissue? Exposed brain is one of the most common causes for near hatch fatalities.

Did you think I needed proof they have a brain?    Yes...I was being sarcastic.... 
 

You never know around here. There's a lot of very silly things that are said and believed.
