I put layer pellet out and chick starter out for my silkies. I have 2 that are about 8 weeks and one that is 29 on layer. The older hen has been eating the oyster shell and pellets randomly, but will eat the chick grower just to knock them out of the way. I noticed the chicks are now eating the layer pellet that has been broken up in the bowl! Do I need to seperate them to get them to eat their own foods until I feed them all the same thing? Is this even going to hurt them? I am wondering if the chicks are eating the oyster shell too? They are given grit.
