My Rooster is NOT a freeloader!! He faught off a raccoon, and if any of his ladies hollars he is RIGHT there to defend them.
I can count on him to a) defend his ladies and b) sound the alarm for me and the hens to hear.
He was possibly going to freezer camp because you don't "need" roosters, but that was before the raccoon attack.
If you can keep him I would! (I'm assuming he's legal since you mentioned the neighbors' roos, and I'm assuming he's fairly well mannered since you aren't complaing about that)
