Sally, I really don't know ages of any of these guys... I have guesstimates. They were a mixed bunch of chicks that my dad got to take to the fair as prize chicks , and then he decided that they were too big when he got some day old chicks from a hatchery. So these guys ended up at my house. This was the last week of June and they ranged from 1 week (my 2 brooder babies) to about 4 or 5 weeks I am guessing. The bigger black cochins are the oldest , they were pretty much feathered when I got them. The others were starting to feather out. These two stay off to themselves and are about the same age, and maybe even the same breed.... (NO CLUE!) They both have black eyes, black legs, and their feathers are black with the green sheen. ETA: the first one does have a few feathers on its feet, where the second doesn't.
