We have owned other breeds over the last 4 years, but this is our frist time owning Muscovies and while 2 have been fine all winter long one muscovy has not.. When is got cold back in Dec poor S'covy started getting cold..at 1st we though she was sick, but has showed no out ward signs, nor is there any wheezing, or anything else that I/we can see or find to suggest that she is sick.. . She is just cold/freezing..then I though maybe Muscovy are not a good cold weather breed, then I remembered..They have Muscovy is Iowa... then we though ok she's molting..which Scovy was at that time.. And so was the Muscovy Drake and our other Muscovy duck Daisy. Along w/them, we had some hens (chickens) and 2 Ancona Ducks also in molt..Yes they we're cold, but not freezing. Poor little S'covy seemed to be freezing and still is.. I have Owned (pet) Birds since 1978 and have owned poultry on and off since 2002, and full time since 2010, so I know how they should act and what things to look for.. I also know a bird that is sick, is usually dead, before it shows any signs.. But again Scovy does not show any signs or symptoms of being sick. she is just a Very Cold Duck..I am wondering if maybe is just has poor circulation but would like some suggestions/ideas. We do bring her in at night when its Really cold, I have cold room in the house we keep her in, and watch her during the day..but I hate bring her is, because that could potentually cause an illness too..but its far better then her freezing to death.. and I just dont have anyway to make something outside..been trying to figure that one all winter.. took some pictures today, Daisy is the 1st 3 pictures and coloring in her beak and feet are a nice 'pink' normal color. Scovy on the other is purple.. so again any suggestion/ideas ??? Defenatly Plan on getting rid of the Muscovy Drake now.. as I dont want any pure Muscovy ducklings from Scovy, because if this issue.. the Drake is a bully anyway..
