I have four new chickens. They are rescues and was told three are hens and one is a roo. Would love to know for sure as they are older and at least two of them crow, possibly three are crowers. Any help would be appreciated. I have seen the gold one crow as well as the Rhode Island Red. The closest two in the picture are the same breed and I have not seen either of them crow but I have heard three distinctly different crows. The RI Red I have seen crow also. The two in the front are the ones I have not seen crow. They have been in my yard since Saturday, Jan. 21. A Tyson truck wrecked and these were part of 65 that my friend rescued. Hoping to have three hens and one rooster.
