This morning when I went into the coop, I noticed one of my hens still up in the roost while the other were off running around outside. I checked her over and physically she seems okay but is clearly not well for whatever reason. Then just after lunch, I went into the run to make sure everything was okay and out of nowhere my always docile and friendly Wyandotte rooster attacked me. He pecked my leg, drew blood and chased me out of the run with high aggression. We have absolutely no history of him being the lease bit defensive or aggressive. I was caught unawares! This roo and the 6 hens are just a few weeks shy of a year old. I don't know if there is a connection between why the hen is acting sickly and the sudden overnight aggression of the rooster. I literally live in the middle of no where where blacks bears, wolves, eagles, hawks and mink share our property so perhaps something happened yesterday that the rooster needed to defend and now his guard is up. I've been reading about rooster aggression and how to deal with it but I'm more curious about is if anyone has thoughts on why this rooster would go from being a docile dude to a raging beast over night?!?
