We purchased this chick at Tractor Supply, as one of 6. Three of them were straight-run Cornish Rocks; 3 were 'pullets'. Two of the 'pullets' I have since identified as Isa Browns; however, this third one has me baffled. At first, it was almost identical to the Cornish Rocks; however, in the last few days, it has gotten black markings on its wing feathers, and has begun to get feathers on its lower legs and feet. According to the bin she was picked from, they could be any of the following breeds: Isa Brown, Rhode Island Red, Black Sex Link, or Barred Rock. However, I've done countless searches, looking for photos of these breeds as chicks, and she looks NOTHING like any of them. I hope the following photos help; if they're not enough, please let me know what else could help, and I'll be happy to oblige. It's not imperative that I know what breed (I already think she's beautiful, no matter what!), but it'd be nice to know. [Also, please forgive me, as I'm new to the forum, and am not sure how to post photos. Let's hope this works!] This chick is approximately 10 days old in these photos (we bought them a week ago), and I also should note that her coloring is far more yellow than she appears in these photos; the flash made her seem white, but without the flash, I couldn't get a good clear photo. She doesn't seem to want to be photographed, but I was mostly looking to show her wing markings, and the feathers coming in on her feet. A better shot of the feet: And a wonderful shot of her wings: One more; this is just a shot of all the chicks, for comparison on her coloring. Yes, she's a little lighter yellow than the Cornish Rocks, but not white [she's the one to the far upper left, right by the Isa Brown in the corner]. This one was taken two days ago [at approximately 8 days old]: The pictures seem to be coming through much larger than expected, but maybe that's a good thing. Again, if anyone could help (even just to tell me that yes, she could still be one of the above-named breeds), I would appreciate it.
