I'm going to stick my neck out and try to explain something, hopefully bestow a little enlightenment.
"Gay" is a slang term for animals, of which humans are one of these, that have an orientation or attraction toward other creatures of the same sex. This orientation occurs in about ten percent of all species. It has nothing whatsoever to do with "thinking" or "performing sexual acts" or sick perversions or morality of any way, shape, or form. It's an attraction, sort of like what a magnet does with iron. It is not a decision or a choice, any more than you decide to be a man or a woman. It just is. No one "decides" to be attracted to the same sex any more than you "decided" to be attracted to the opposite sex. It is just the way things turn out.
As for whether anyone else has had a rooster who has had this attraction for another rooster, yes, I know someone with two roosters, one of which wants to mate with the other rooster, and has no interest in the hens. However, the second roo is average in his orientation to hens, and firmly discourages the first rooster from mating with him. Oddly, the two roosters get along extremely well with each other, except for settling this "conflict" every so often.
It's really no big deal.
