1. Most of the 3 week old babeis have no tail feathers. Does that mean they are roos? Most have the lighter color legs but one has darker legs, no tail feathers and the start of a bigger comb (Dominiques) 2. It looks like I'll be chicken sitting for the winter. How can I make sure I can tell my hens from the others? They're all Dominiques. Are leg bands good or not? 3. How many babies should be kept together for warmth? They're three weeks old and I want to give the ones away that are promised but I don't want to have so few left that mine get sick or something. 4. We have 9 full size hens. Hubby wants to keep two roos through the winter to be sure we have a roo that survives the winter. The roos are the babies right now (3 weeks old). Will it be bad to keep the young roos when they are near full size with the hens? How old are roos when they realize the hens are hens? Thank you in advance for any help!
