I sometimes put my chickens out in tractors while I am home during the day, and I was wondering if a cat would dig under the frame to get to them? I don't worry much about other predators since my yard is fenced to keep dogs out and I would never leave them in a tractor at night. Just wondering since the cat population is getting out of control with multiple stupid neighbors feeding strays but not getting them fixed. One was stalking around their run yesterday stressing them out. I know the run is secure and it could not get in but just them being stressed made me really angry and made me wonder how safe they are in the tractors. If you have had problems with cats how did you deal with it?
They aren't a major predator of adult large fowl but they can and will kill if they're hungry. They'll take chicks and possibly bantams just for the fun of it. https://www.backyardchickens.com/t/261440/the-worst-predator They will stress them out but they normally won't dig. Dogs and foxes will dig. A fox can easily jump a very high fence. Raccoons, mink and weasels, though normally nocturnal may be afoot during the day. A raccoon can climb virtually anything. The mink and weasels don't need to since they can squeeze through a 1" opening.
