About how old until I can get some idea of gender? I guess they're about 3 weeks now. They all have flat (rose?) combs, that all pretty much look the same- some are skinnier, some wider but none of them are raised at all. Ive never had any type of wyandotte before, so I have no idea what to look for. Here are some (not so great) pictures, if they'll help. Thanks for any advice you can offer, even if its just to wait a little while longer
