Puzzle time... and no pictures either, since I don't have enough posts yet! Recently got my first batch of day old chicks. It included Barred Rock, Dominique, and Cuckoo Marans (2 of each, 6 total). 3 of them were DOA, so I now have 3 unidentified black chicks. They started out looking exactly the same. Similar spots and coloring, and very heavy black splash down the unfeathered legs, so much that I really can't tell if the legs are more white or pink or yellow. They all had a small white head spot, white tipped wings, and white bellies. They aren't old enough yet to see the normal differences (rose comb vs. single comb, etc.) Since 3 out of 6 died, I could have one each of the three different breeds. But it's equally likely I have 2 of one breed, 1 of another, and NONE of the third. I know the BR is closely related to the Dom, but not sure whether they develop at similar rates. At just 2 weeks old now there are some major developmental differences. Mostly in the size and the tail feathers. I have two that are almost identical, and quite a bit larger than the third one. They also have very large tail feathers nearly 2 inches long already. The third chick is much smaller, and only has the hints of a beginning of a tail rump bump. Definitely no tail feathers yet. It's also much more of a silver-grey as opposed to the dark black of the other two. The third (small) chick is also far more aggressive towards the others and flighty around me. The two larger ones look very much alike and they are both noticeably more curious and friendly towards me. Does any of that help you all rule in, or rule out, one of the three breeds? I would think the dramatic difference in tail feathering at 2 weeks would be a good clue for someone who knows these breeds, and maybe the size difference too. All of them seem to be eating equally well. Thanks for any help or advice you can offer!
