Our school hatches chicks every year, this year I had the joy of teaching in a room with some chicks and was fortunate to have a good batch in our room. We only had 1 that had a very difficult time hatching and at lunch day 2 I helped the little chick out. When the kids went home for the year we had a "hospital" box of chicks that were in bad shape. I took that box home because my wonder chick was in there and knew with a little TLC he/she'd be ok. That wonder chick was the only one who survived and is my little "red" who needs identifying. I tried the wing sexing early on and self determined I had a roo, then I read if there is a black stripe down a RIR it's almost always a pullet, but then the feathers were really late to come in so now a roo, but now the comb is still yellow at 6 weeks so pullet, but yesterday "red" was either having a hard time swallowing an ant or going thru the motion of crowing....any educated guesses on the sex at this point would be really helpful. My kids and I really love our bird, and we have a great home set up if "red" turns out to be a roo where he'll have his own flock, but if "red" is a pullet then I'd really like to start the work on the permanent home for her. Thanks everyone!
