We have some bodacious squirrels in the neighborhood and one has figured out how to get in to our chicken run. So far, we think he/she can not get into the hen house; the girls are closed up in that at night and squirrels are not nocturnal. We take food up at night but it's out in their pen during the day for the girls. One of our young hens, they're all 12 weeks old, has chased the squirrel around the pen (it was quite entertaining to watch) but the squirrel didn't leave until I entered. Should we be worried about the squirrel preying on our hens? I know they will go after eggs but, we hope, when they begin laying the nesting box, in the hen house will be secure. Meanwhile, we will try to shore up where the squirrel is getting in. Just want to know if squirrels go after hens?
