Is it too early to switch my 6 and 1/2 week old girls to grower? The reason I ask this is because I have 8 and 1/2 week old girls that are eating grower, and the younger girls are still eating starter. Because of this I have the young girls in their own pen in the coop. I feel bad because they're confined while the big girls get the run of the place!! So what I want to do is combine all the girls, get rid of the little pen, have ONE feeder and ONE waterer and I don't want to wait another week and a half to do it!!! What if I mix grower and starter together for all the girls for one more week?
