Sorry to post twice in a row, but I lost a 6 week old poult last night from inside the brooder.
I do not think I have a weasel problem. I am thinking possum, now.
This brooder is the first one I made. It is made out of 1 inch chicken netting which a weasel would go through. I had 20 chicks in the brooder a weasel would have went in and had a heyday. This bird was up tight against the wire netting with its head removed and a wing gnawed on and partially missing. It appears whatever it was could not get into the tractor/brooder. The birds think they are too big to sleep inside the brooder part, so they sleep next to the wire.
It explains a lot to me. The first Cochin that was attacked was in the creamettes run, which is about 60'x10' of 1 inch chicken netting. I am guessing now she was next to the netting and something attacked her taking the top of her head and could not get in to finish her off. Which explains why she did not die in that attack.
The second cochin was in a different run that a possum could have gotten into. I am guessing she refused to roost and sat next to Bert on the ground when she was attacked. Why Bert was not killed is beyond me.
I will be setting traps tonight Live traps and jaw traps. I will still set a weasel trap in my new box with a mouse for bait, just in case.
If not a Possum I suppose a mink, or skunk could be it, I doubt a fox could reach through 1 inch netting. I have no fishers here I am too far south, same as martin. Any other Ideas?
