Being a first timer...the issue I am having determining my chickens gender is that they are all different mixed up breeds...the eggs came from someone with 80 different mixed breeds selling eggs for consumption... They are now seven weeks old and I think it is becoming obvious that I have three males and one female. I could be wrong though because I have no comparisons or previous experience. Can you tell from these pictures by just looking at the comb? Their tail feathers look the same on all of them but one.... ...... I named them all female in the hope but........Help!!!
