My chicks are 4 weeks old and I just put them in Gen Pop (as my DH calls it). They are in their own fenced area but it is inside the field so everyone can see each other and get to know each other. They are sleeping in the main coop too but again, separated so there is no physical contact between the adults and the babies. At what age do you switch from Chick Starter? What do you feed them after the Chick Starter? When can they have fruits and veges? Thanks in advance for your input.
