I have 4 pullets that are nearing two months old and are ready to be moved out to the "big girl" coop with my other full grown hens. I say they're ready meaning they are fully feathered (of course) and the temp at night isn't going below 45 or 50. My only concern is that I have no idea what to do about the feeding situation. I can't separate the big girls from the little ones once I put the pullets into the coop, so essentially, they will all be eating the same thing. Should I just mix in chick start with the layer pellets and hope the mix will do for both groups?
