I think you're right in their place in the ranking there--# 1 is your best of that bunch so far-- is going to have beautiful hackles! His tail looks similar to his dad's, not solid like a couple of the others, but definitely on the dark side. Did you get any with just 5 comb points? Even if #1 has six points, he's your best one at this time. It's still too early to pick your final one, but you could probably narrow it down to three or four. Gracie has a great comb and I was hoping you'd get at least one boy that would be as good as Isaac and have that great comb Gracie has.
#2 and 5 have nice tail barring. I'd say that #3, 4 and 6 would be culled if they were here. I don't see them improving enough to compete with the others, from those pics, anyway.
****I sent Janet the link to your post and she agrees that #1 is very good. #2 isn't bad, but you may have better luck with that second batch you hatched, Kathy. The rest are not up to snuff for sons of Ike. Just the luck of the draw, genetics-wise, I suppose! How is the second batch coming along?
