My problem is I have 5 10-11 month old hens and 4 2 month pullets. We don't have a way yet to separate them so we can feed them separate feeds. So I've been giving them all laying feed. Will this hurt the pullets? Stunt their growth? Will giving them all chick feed make the hens stop laying? Argh. We should have our yard partitioned next week so I can separate the girls. Help!!!
