. As far as feeding “dead wild critters “ to my chickens that’s a negative for me. Too much of a gamble of passing parasites/diseases. It’s not worth the chance.

Yes we never know what those chickens are eating when free ranging but I’m not comfortable introducing any health gambles intentionally myself. Just my honest thoughts on subject.
