The neighbors(I swear there have got to be twenty people living in that house) have chickens, for whatever reason. I doubt the roosters are used for fighting, since they've got quite a few hens.
Anyway, they must have some kind of brain damage. They crow 24/7. Nothing like trying to sleep when roosters are crowing all hours of the night. >_>
If fortune should ever strike, and all twenty of the people in that house are away, I'm going to fry up every last one of those roosters. I don't care if they're as tough as shoe leather; the satisfaction alone would be well worth it.
