We use the battery powered ones too. FUnny though, but the hens won't touch the fried mice. But the trapped ones, yes, we toss them to the hens. (No poison here, just peanut butter.)
Interesting. I wonder why they won't touch the fried rats? Good to know someone else thinks it's OK to feed dead rats to the chickens. I don't have a rat problem, but I think I'd trap them and feed them to my chickens.
I used to live in a house shared with mice... I found peanut butter on the traps worked the best. Cheese never worked as well as the peanut butter for us. Too bad I did not have any chickens at that time. Could have fed them some good fresh meat.
