While I was away on vacation last week my house sitter called and said that there was a raccoon in the tree that sits in my chickens' run in the evening just before dusk while the chickens were still out. My dog went absolutely crazy and the raccoon ran off to the back of the yard away from the coop. There the coon got fiercely squawked at by a bunch of crows who must've been protecting a nest. The raccoon has not been seen again. The run is enclosed and dog-proof but it is not covered on top and with a tree in the run it would be tricky to do. The coop is built like Fort Knox and the chickens are locked in at night but during the day they're out in the run. I told the house sitter to keep them in the coop until I could figure something out. Now I'm home and I'm wondering if I need to figure out some way to enclose this run or if my dog and the crows taught the coon a lesson. I'd love to be able to let the chickens have free range over the whole yard during the day. I figure if I could let the dog and chickens out at the same time they'd be protected but I don't quite trust the dog yet, but that's a different post. Anyway, I guess my question is -- Do I need daytime predator protection too?
