I've got three 9-week-old speckled sussex chicks that were raised by my broody hen. They are still small enough to get out of the chicken run and run around in the yard a lot. For a few weeks, this was great. It made it possible for me to put their starter/grower feed outside the run, where the big girls couldn't eat it. So the chicks ate a lot and grew. But now, they don't seem to even touch their feed. My only guess is that they're eating layer feed and whatever bugs they come across in the yard. They're growing and seem healthy, but I want to make sure they'll be okay, as I've always heard only to feed them layer pellets once they start laying. I don't have enough room to totally separate them from the other chickens. Thoughts?
