I now have 6 chickens, and finally it's an all girls club! But, to complete my flock, I took some chickens of the hands of a lady who getting rid of some younger pullets. I have two 6month olds (an BA and Maran) one 5 month old (BA), one ~1 yr. old (Ameraucana), and the younger ones are two 4 month olds (a BA and Delaware). I have two now that are laying, and one will be anyday now, and three that won't be for another few months. I still have chick starter in there, what should I move onto? By the time this bag is done, can I switch to layer feed? The younger ones be 5 months old at that time. I'm confused. Anything will help, thanks!
