Hi there... Daughter has asked us to border her two "babies" for a moth or so till she figures out what to do with them. She thought they were silkies...I'm not so sure. they are about 2.5 to 3 months old. I'm not a chicken expert...actually, I've VERY VERY new to this. the dark one has a single comb...and no real poof on the head...but, kind of a mohock. He has feathers on the feet. His feathers seem more like feathers and less like the "fur" that a silkie appears to have. She thought he was a cockrel...I'm not so sure. his tail feathers are short and don't seem to "flow" like a rooster's do and the neck feathers aren't as long? The light one has the poof on the head...but, the feathers are, again, feathers and not so much fur. She has feathers on her feet...but not really very much. I do think she is a pullet. Here are some pix...but, not sure you can really see what you need to...hard to get a good pix of a CHICKEN!
