I got my first flock over the summer: 12 "Rhode Island Reds." There are 10 I'm confident are actually RIRs, but these two I'm not so sure about. - They are much larger than the RIRs: maybe an inch taller and a good 1-2 inches fatter. I poked their chests once, and there is definitely some good meat there. - They are about the same age as the RIRs (7ish months), but their combs never got any bigger. Redder, yes. Bigger, no. - They're very antisocial, both with the other birds and with me. My RIRs all gather around whenever I get in the run, but these two just hide and avoid me as much as possible. - Any time I successfully pick them up, they struggle like crazy. They're the only two who will not calm down and will not give up until they're back on the ground. - They're on the bottom of the pecking order and stick out like sore thumbs. The one with some tail is second from the bottom; the one who looks more tail-less is at the very bottom. The feed store where I got them suggested that they might be Production Reds? I'm also not actually sure they're laying. I get about 9-10 eggs per day, and I've just been assuming that these guys are the slackers, but I don't know how to check whether or not that's really the case. I know you can tell by comb color, but since their combs are so tiny I'm having a hard time comparing them. If they're not producing, I want to cull them. They really seem more like meat birds than layers. And if they are producing... well, what the heck are they??
