I recently rescued a pair of friends. A collie with a chicken. They are best friends & want to hang out together all the time. my question is, what breed or cross breed is the chicken & is it a roo or hen? I have never seen one like it. It is very friendly & aprox. 4 months old. (Not sure because it came from a dog rescue that knows nothing about chickens, only that they didn't want to separate them because of their close friendship.) It is a smaller sized chicken. Any help would be greatly appreciated.
