I have a two and a half week bantam cochin, adorable little one, it will let you pick it up and will sit in your hand and be very content but in the brooder it seems to be very assertive, runs and belly bumps the other, much larger hens and ones that are turning into roos...as well as staring them down. It is SO funny to watch cause it is so small but does this mean my little Dot is a boy??? Or can hens have this behavior too? I will be super sad if it is cause I hand picked it out, being the smallest one there in the straight run bin! His comb is still pink but his little waddles are turning pink! This was last weeks pic.
