I have been having allergy symptoms to everything so bad that now take allergy med nightly and flonase every morning if I dont my throat swells and is very painful. I was told that ducks were different than chickens as they have oil glands but need to know about cleaning after them in a coop before I switch to ducks. Yes, I still have 7 silkie/showgirl hens and 6 six week olds. I dont really want to let them go.
