I have 9 chickens that are 6 weeks old, I thought I knew which ones were boys and which were girls but now they all seem to have combs and I am afraid they are all boys. I really do not know the breeds and I think a few are probably mixes. Have any ideas? I really can't keep more then one roo so most of the boys will need to find new homes as soon as possible. Sorry for the bad pics, I can take more if it will help.
