i have 15/16 week old chicks, and im looking to move them in to the big girl pen. when can i switch them to the layer ration without hurting them? also, i have a banty that has gone broody, and no roo. i ordered her some (copper maran!) eggs, and plan to let her hatch them. do i *need* to seperate her from the rest of the flock? or can i leave her and her new babes in the big girl pen? how will the whole feed situation work out there? i guess im looking for some expertise advice thanks in advance for the responses. BYC has benefited my flock so much. . . . so much help here, and wonderful community!
