I think i probably know the answer to this. I currently have a flock of well established free ranging chickens. I happened upon the delightful notion of getting a pair of muscovy ducks just yesterday. I did some looking and some research, and someone nearby is offering me a male and female pair, the female of which is sitting on a clutch of eggs already. Oh, and that's for $25.00. He is apparently getting out of farming and animals and is ready to liquidate. I had originally planned to get fertilized eggs and hatch them here so they would grow up with my chickens, etc., etc. But the idea of this instant gratification for $25.00 is very tempting. I was just about to talk my husband into it when i remembered that they should probably be quarantined before they mix with my chickens. But i don't really know how the spread of disease works between ducks and chickens. Will someone please enlighten me? Thanks!
