Title says all-my "blue" *I think he/she is black!) silkie has developed a gnarly grayish looking comb over the last three weeks and also started to crow. Any way it's a girl, or should I find a new home?? (If it helps, we did have a rooster in the flock but he went to his new home about the same time that this chicken started to grow a comb. It's approximately 19 weeks old now.) Poo. I initially purchased 8 birds but figured one or two would be roosters so I shouldn't be surprised, but I was thinking I'd end up with more eggs! Thanks!
