I have tried to find this information elsewhere on the site, but always seem to get sidetracked by a million other interesting things... so I thought I would try asking directly. Please forgive me if these things have been asked and answered a million times. I'm still a bit new at this... I have some Lavender Ameraucana chicks, and I'm wondering : What is the correct eye color, and is it displayed from birth or does it develop later? I've read things mentioning correct or incorrect eye color, but couldn't find a description. At what age do their cheek muffs fill out? I've also read that some are missing the muffs. Mine are currently at an awkward stage in their feather development, an look a bit moth-eaten, so I can't tell. Is there hope? Is there an age when sex becomes apparent? I've got one whom I've known since 4 weeks of age was a roo (he's my avatar, about 5 or 6 weeks old in that picture), two that I'm pretty sure are pullets, and one who is still ambiguous. He has a more developed comb and a bit of dark pink at the base of his beak, but then these two features stopped progressing about ten days ago, and he's become hard to distinguish from the two pullets. Last question--if they do all have cheek muffs, is it bad to keep a rooster with the hens? I read somewhere that it's not good to breed two birds with cheek muffs, is this so? I promise to read up on it before allowing any breeding to take place, but I would love to keep a roo and have more of these sparkly little chicks. They are just so lovely. Thanks! I really appreciate any answers anyone has time to give.
