My silkies have just started laying eggs and I noticed that one of them has an egg stuck to its bottom! The egg is cracked. The hen doesnt seem affected by it though. It doesnt look like it hurts her atleast. Why does this happen? The silkie is very fluffy! I still didnt switch to laying pellets yet because I am still going to finish off a little grower mash. Tomorrow Im going get laying pellets and will feed them more oyster shells. Could the egg get stuck and crack because it has a thin shell?
