I have had chickens a little over a year now and Sunday was my first tragedy. Around 8:00 am on a bright, sunny, morning. I heard my chickens raising a fuss. I had 7 hens and three roosters, all free range on our two acres - until now- in upstate New York...I found my lead rooster and two of my hens in the front yard raising cane. Found three hens laying in the chicken coop -safe. Found my young rooster in the yard - dead..he was pure white and didnt have a mark on him - no blood, no marks. Also gone was my other rooster, one white hen and one black hen. All that was left was a yard full of feathers that spread in several places across the field behind our house. (we don't have any close neighbors) It took quite a while to get my remaining family back into the fenced in area adn get them calmed down. The next morning, after I let them out of the coop and fed them, I heard a faint "cock a doodle do" from my front yard. I thought I might be dreaming but after the remaining rooster and hens started fussing again, I heard the faint sound again. Lo and behold my other rooster was hiding under a large pine tree! I coaxed him out and he was very shaken and minus all of his tail feathers! I coaxed him back into the coop and he is mending. (no physical wounds - just shocked and a cold butt!) SO now we are wondering what would attack in broad daylight, with no blood etc? Please Help with any suggestions on the predator (s) ! My chickens are in the chicken pen but not very happy as they are used to being out and about.
