We got our chicks from Tractor Supply back in April. They had the brahmas labeled, but not the white chickens. I was hoping I would be able to figure out their breed on my own, but my google-fu has failed me. They're about 16 weeks old now and it is driving me mad that I don't know what they are. This one appears to be a splash variety (we thought she was perpetually dirty at first!) she's got 4 or 5 dark brown marks on her wings/back that originally looked like someone pooped on her! I struggled to get a decent shot, we had just moved them to the newly completed permanent run and they were running around enjoying the extra space! They're mostly white, with creamy to ivory heads/necks, and a few have ivory across their breast. Any idea what they might be? I live in MN, so I'm guessing that they would stock a cold hearty bird since our winters can be pretty fierce, if that might help narrow down choices.
