I need y'all's help. Something got in my large fowl pen Friday night and killed all 15 of my birds. That pen was an assortment of breeds and ages, including the six I had gotten to POL from this season. Even the rooster was dead and he was a tough cookie. I got home after midnight Friday and didn't go out to lock the coops up. I don't know if it happened before that point or after that point. Either way I'm just sick over it. This was the pen of chickens I have had since I started.
I found all but one of them in the food shed between the roosting coops. The other was out in the run. I saw no obvious damage to them. One was completely missing. They were scattered throughout that shed (4' deep x 8' long and about 3' high). None of the other pens was affected. The marans who likes to roost up on top of the run was fine. The spangled sussex that got stuck in the banty pen was also fine. Just those in the LF pen were affected.
I'm assuming that this is a predator. I have set the live traps for the last two nights and had bait stolen the first night and the trap disturbed the second night. I have been fighting possums all summer, but this doesn't seem like a possum attack. Weasel perhaps? It could be raccoon since I know they are around. None of the birds were decapitated though. They were just dead.
The other options would be illness or poison. No one has acted ill and I've seen no evidence of sickness. None of the other pens have been affected and they all touch each other. The birds were all different breeds and ages, so it would be odd that an illness would just touch those 15 and none of the other pens.
If it were poison I would have expected the birds to be scattered around the pen instead of all up under the shed. Plus the two that lived would also have gotten into whatever might have killed them. Everyone was absolutely fine when I left for work Friday morning.
What could have done this? What am I missing? Do y'all think it was a predator? How do I catch this sucker? It needs to die.
