If I do eventually free range my chickens, I plan to do it in the horse pasture. I have a mare who doesn't chase our dogs or cats, but I have seen her chase foxes and coyotes out of their pasture, and one time my husband had to pull porcupine quills out of her nose! I'm just waiting for her to get skunked. Anyway (I get off topic so easily ), has anyone had trouble with their horses chasing their chickens, or do they pretty much accept them as just another bird? I'd hate to come out to squished chickens.
