I'm new to Backyard chickens and new to chickens. Started in April of this year with babies, I have 5 favorelles, 4 chanteclers, 3 americaunas, 2 barred hollands, 2 jersey giants, 3 silver lakenvelders. And I repeat I'm brand new at this, so in July, I obtained 5 buckeyes, 5 speckled sussex and 5 welsummers. I have a very knowledgeable person at the local farm and garden star and she has helped a lot. I never asked whether it was a good idea to get the second group of chickens or not. I never gave it any thought about how to integrate these two groups. I keep learning. They are now mixing together without problems, the little ones are able to get away from the big ones if needed. However, some of the young ones seem to like the layer food better than the grower food!!!!! I feed them both organic and supplement with vegetables from the garden, they get a little scratch once a day. I was going to raise the older chics' feeder higher, but the buckeyes and sussex are already as tall as the lakenvelders. Is it harmful for the young ones, who are 9 weeks old, to be eating layer food, instead of grower? And I please let me know if I should put this post in a different area?
