I'm almost positive at this point it was the rooster, I've been reading up on predators and coons pop the heads off mostly, weasels suck the blood, never in my three years of living at my house have I ever had a chicken disappear. Also, if it were a predator it would have been back by now, or at least have some evidence of the attacker, if indeed the the rooster did help. It's all too coincidental that the day before that rooster was showing dominance, crowing and flapping his wings together and puffing out his chest. This has been a problem now for 3 months but he never got that close to our chickens just hangout crowing in the drive way (which is also another sign of dominance). Only 3 days (in a row) had he been interacting with our flock, he wound run to them. He only has 2 hens of his own and he prolly got bored. But from my experience and what i've read, roosters need 15 to 20 hens, and the more a rooster crows the more dominance they show. My drakes and rooster would not go near this rooster and my drake was attacked near where I feed them. I'm pretty sure my drake was just trying to eat and the stupid rooster was being territorial. I know what roosters are capable of because I had to get rid of a rooster because he kept chasing and attacking my drake. I called the police because he was back in my yard yesterday, but was acting strange and not coming past the driveway again, and the police said I can't kill it or trap it because it's someone else's property. All I can do is build a fence at my expense. It is really upsetting the whole thing, but regardless if the rooster killed my drake or not, which I'm pretty positive he did, I don't want him in my yard and at this point I'm just looking for advice on how to keep him out that's not going to cost me a fortune. Building a fence around my 3 acres is just not realistic and even if I did pin my flock up I don't want the rooster at my house waking me up at 6:30 every morning! What should I do about that? The police said I can't trap him and set him free somewhere because that's "stealing someones property" and I can't kill him because "that's animal abuse". I just got so mad I hung up on him, I pay taxes on my property and I should have a say on what to do with trespassers. I have asked my neighbor over 5 times (both over the phone and in person) to keep him locked up....
