Instead of getting eggs when my hen went broody, I bought day old chicks. The feed store said they were 95% certain the chicks were female. (How can they make that claim at that age?). I put them under my broody and she has been a wonderful mom. (By the way, I would never have attempted this if it wasn't for all the great information on this website). Now they are 10 weeks old and I'm starting to think I may have a roo. Mainly because of its behavior. He/she will run up to the others and puff the neck feathers and stand real tall. Just briefly. I think they're playing. Do females do that? All four are the same breed, Rhode Island Red. The one I think is a roo has more black coloring in the tail feathers. Here's a picture of the one I think is a roo I think these two in the foreground are hens. Daisy in the background is my oldest, my sweetest and my best layer right now. Unfortunately, all the others are skittish.
