With respect to low spouse impact, you do realize that YOU will be doing the feeding, cleaning, medicating, etc., right? Not your spouse?
My husband doesn't mind my chickens. When they were fluffy adorable babies, he was diligent about handling them and petting them so they'd grow up used to humans, and he only complained occasionally of their smell (brooder box in the spare bedroom). Now he is willing to pick up a bag of food for me on rare occasion. He chicken-sits for a few minutes here and there when I let them range around the yard. He helps me chase them back into the barn when I am done letting them tear up the yard. Once in a while, he is willing to help with things like wing-clipping and nest box building. But if I ever asked him to, for example, actually shovel out the coop and put down new pine shavings, or refill their feeder and waterer, or medicate a chicken, forget it. He refuses to do the one chore he initially agreed to (slaughtering excess roosters). He especially does not clean out the fridge and feed the 3-day-old leftovers and expired yogurts to the chickens, and you would think that would be a simple chore for the person who does all the Tupperware-washing.
Ironically, he loves watching my noisiest two roosters, and he crows back at them sometimes to make them yell louder. Yeah, our neighbors love us.
