We had 2 roos and 8 ladies. All free range. Woods near the coop.
Here's what we know:
Yesterday afternoon--chased a shepherd from our yard while it was chasing a chicken and seemed super hyped up.
I didn't have time to investigate much at the time and assumed the other chickens had just gone to hide in the thicket in the back of the property like they usually do when threatened.
Yesterday early evening--Went to put the chickens in and 5 were missing. 1 dead in the coop. Back end of the chicken missing and an egg half exposed. Feathers all around. Other chickens skittish. More feathers (different missing chicken) found in a clump and a trail starting right near the house (almost two acres from the woods) and going back toward the coop/woods. All our wooden eggs had big teeth marks in them and one was carried several yards from the coop. [Dog or other predator?]
Today--chickens out (because we thought it was just the dog plus spooked birds who were in trees for the night). All 5 that were gone yesterday were still gone today all day. Two more chickens (one roo and one hen) went missing in the afternoon. We found the roo in the woods after a feather trail. The back of the head and neck and some of the breast was eaten. We found two more distinct feather clumps and trails in the same area of woods going toward a huge brush pile but no more carcasses. There were a ton of feathers from both of today's missing birds in the coop and right outside the door too. So, it seems like they may have been trapped and killed there.
By tonight, we have 1 roo and 2 ladies left.
So, it seems like we had a nearly simultaneous dog attack and wild predator attack yesterday. But we're not sure if the first dead bird in the coop (back end missing) and egg damage was the dog or the wild predator. Obviously, how we approach containment issues with our neighbor's dog in future would be impacted if he was just a tease versus a killer... And we'd like to trap whatever other thing is after the other chickens in the woods.
