I bought a 50lb bag of layer 16% mash and my chickens havent laid an egg yet. I have two that are 8 weeks old(silkie roo and an ee pullet) and eight 16 week pullets. I was orginally looking for chick feed but the feed store had ran out and only had this left. I asked him if it was okay to feed chickens that are above 8 weeks old and he said it is perfectly fine. Now im worrying because i read a forum on here that talked about feeding layer mash to chickens that arent laying yet can cause kidney problems and such. So...can i feed this to my chicks or do i need to purchase another bag of feed. idk what kind of brand this i, but its called superior animal nutrition "extreme feed"
