How much does a chick eat at different ages? I am getting 10 chicks this week and I have 50# of starter ready for them. Can someone tell me how fast they'll go through this? Will this last the whole 6 weeks that they should be on starter? How fast will they go through the grower after that? I order their food so I need to know a month in advance when to get more and I'd like to keep it as fresh as possible so I don't want to order too much.
