We lost our buff silkie, Lucy, today. Not sure what happened, but I checked on her last night and she was fine - frisky (she pecked me when I tried to pet her) - but fine. This morning, I went to feed them, and she was laying still in the nest box (which she never gets in). When I got home, my fiancee had buried her. Yesterday, it rained all day with higher than normal winds, and last night the temp dropped to 30 degrees. Are silkies more susceptible to cold weather? Our black silkie seems fine so I don't know if I should give the rest of them vitamins just in case Lucy was sick or just hope that it was the cold?? I am unsure as to whether I should put any type of heater in there since it really doesn't get that cold - only once every couple weeks. Any advice (other than necropsy)?
