Many animals will kill multiple prey species, at one location, if the opportunity arises. Wolves often kill multiple deer in winter yards, when the snow gets deep and the deer are already stressed. I've witnessed a Bauld Eagle nest with four muskrat tails hanging over the edge, a mink that killed 6 geese in one pen in a single night, same for a raccoon except 9 ducks, a weasel that killed 5 chickens (tore the throat out of all five) and crippled another. Coyotes are notorious for their efforts killing multiple sheep. I trapped a Fisher that killed 17 chickens in one night, when a young kid was watching them for a vacationing neighbor, and left an entry ramp to the coop open. A guy called me a couple years ago, wanting me to trap a Bobcat that had killed a doe and fawn deer, and covered them up right in front of his trail cam! Their deer party had watched the doe and fawn all season and gave her a pass. She was a runt doe they called shorty, and only had the one fawn. Lots of stories about Otter families, eating whole populations of pen raised catfish in rearing ponds. I believe most animals are opportunistic and eat whatever they can, in whatever quantity they can get. Might be a long time before their next meal.
Paul,
Did you go to the Ia convention? I caught the Facebook link on Tman where Groenwauld gave the fur forecast. Sounded pretty bleak, unless you have a good coyote. Fur Harvesters sale fox sold at $4, most beaver withdrawn. Tanneries are still about six months backlog.
