I have a couple of 3 yr old hens. I'm in the process of downsizing so these little gals will be the end of chicken husbandry for me. In all my 71 years, I have never experienced 'fart' eggs until,these gals. Perhaps they were laid in the woods in my earlier years but never, ever in nests. I understand this is an oddity and happens occasionally but,, has anybody ever had a hen that did it on a regular basis? I am most certain I know which little gal is responsible for useless oddity but getting rid of her for her misfortune isn't an option, they are such buddies. My question is just that, does anybody have a hen that lays nothing but these tiny good-for-nothing's? On occasion I collect, scramble and feed them back.
