I doubt a red squirrel would harm a chicken, highly doubt it, they are not meat eaters. Chicks on the other hand I don't trust them, I've seen red squirrels kill and take off with birds out of a birdfeeder, why I don't know, maybe protein deficiency?
Weasels will eat mice and rats, probably a rats worst enemy. My father-in-law swears they won't harm chickens, he had one he fed pieces of hotdogs yrs ago, never bothered his chickens, only had problems with opossum and raccoons.
I know better, when I was a kid a weasel over a three night period took out almost all of my father's whole flock, over 30 chickens, just took their heads off.
