My almost 4 month old Polish just passed. When i came home from work she was laying down barley breathing.. she all of a sudden starting ruffling her feathers and her head started turning back and all different directions. Then it stopped.. this happened 3 times and about 30 minjtes later she died. Yesterday she was laying around sleeing all day but i thought it was normal due to me and my husband working on the coop all day and it being hot out. Is this a Sceizure for just normal as they are dying? I have had 4 polish in tje last 2-3 months and they have all died on me.
