Late this morning I went out to check on the birds as usual. Itās very windy and gusty today. Iāve had to chase down gutter spouts and sleds the kids forgot about
I peeked in the guinea coop expecting to see the guineas hiding in there from the wind. The flock was gone except for one lavender guinea laying down with its head between a nest box and the wall. I had remembered seeing it there when I locked up last night. Right away I knew something was wrong and ran in to check it out. I thought he was dead already. His body felt really stiff.
I gently picked him up and realized he was alive!
I brought him in and looked him over for injuries or breaks and couldnāt find anything! He was fine yesterday! Shortly after setting up a temporary box for him, he died
The rest of the flock seems fine. Everyone is very actively doing guinea stuff in the yard. I havenāt noticed any major aggression between males, then again the wind has kept me from spending very much time outside with them. I just donāt know what else it could be.
He was actively hanging out with another lav male and female yesterday.
The only thing I did different last night was I left a window open. The wind was blowing from the opposite side of the coop so I thought it would be fine. These no way he got too cold, right? Temps were above freezing,but still in the 30ās.
Ugh, I feel so awful

From your description, it kind of sounded like he was stuck, but I guess that wasnāt the case? There are so many random things that could have killed him... My state diagnostic lab will do free necropsies for chickens but not guineas, so Iāve been reluctant to necropsy. I did submit one hen last year, and she ended up having a reproductive problem. Did your guys keel feel thin? That would indicate a health problem of at least a week, I would think. He might also have eaten a string or other foreign body, since it sounds like you have new stuff exposed outside from melting snow?
