Hi -- I have five RIR chicks about a month old. Three of them look like they'll be roosters, one is smaller and is likely a pullet, and the littlest one is less than half the size of the others. I'm worried about her. I don't want to separate her for a couple reasons, but she's one of my only girls and I don't want to lose her. The others don't seem to be denying her food, but they do trample her from time to time. I'm thinking of separating her with, perhaps, the other female and giving her high protein food. Good idea? This would leave the three suspected roosters together. We're not sure what we're doing with those guys. Also, since she's so small I worry about giving her food she can't digest. I guess if she's got grit, I should not be concerned about this? What kinds of food should I give her?
