I have 1 surviving chick from my last hatch. at what age can you sex them she(ihope) doesn't have any comb what so ever. very bonded to me, she is sitting on my arm singing songs to me. I feel bad when I have to put her back in the brooder she cries and cries but she can't be loose in the house dogs and cats would eat her. she is about the size of a large sparrow. I she is a roo she will have to go at least someone will have a very friendly roo. I'll try to post pics sometime.
