I have spent days reading through this thread. What great info and pics!
My 4 "girls" are right now 3.5 weeks old. When I got them from the hatchery they all were basically identical. Same sized and shaped head spot, same wash down the legs, same size. Now at 3.5 weeks they are starting to feather out and 2 are lighter coloured than the other 2. I did order pullets but, I am beginning to wonder if I got some roos. I am not opposed to a roo since I had thought I'd need to get one next year (to keep my flock together and "protect" them from being absconded by the roo 3 houses away)
If I manage to get some pics would it be worth the stress to them (they don't really like being handled much right now) or are they at an age that is difficult to tell at? I am wondering but, being unsure is not stressing me out or anything. lol.
