I have 3 Muscovy drakes who we got from friends mid to late summer. They are not very sociable with me and will not let me touch them. They have a house which they refuse to use and I have been unsuccessful at herding them into it. They have been sleeping in their run on a thick bed of straw I have made for them. One of the drakes, Will, has what I think is frostbite on the caruncle at the top of his bill. The area a light orange and I have noticed when I do night checks that he does not sleep with his head as far under his wing like the other two leaving that area exposed. My husband has tried helping me catch him but we have not yet been successful. What in the world can I do for this poor guy? I have tried feeding them treats to gain their trust but they act like they don't even know what they are or what to do with them. Does anyone have any advice? I am worried sick about them with these horrible temps we are having.
