Well, I started with five barnyard mixes, a cross of buff orpington, black australorp, and Rhode Island Red. But the man hand bantams on his property, and I think we ended up with a bunch of bantam barnyard mixes. Then we have a black copper marans, and five speckled sussex in quarantine.
I have no idea on any of their ages; the original five we've had for three weeks. I've gotten a lot of guesses...
Most of their combs are getting color and wattles are coming in. Only the biggest barnyard girl and the BCM are fully feathered. I can fit at least one finger in the pelvis on them all, and some have a little more wiggle room than others (finger and a half?).
I don't regret not starting with babies, because I don't think I could handle waiting that long. But I do wish I knew how old they were.
