I came home tonight about 10:30 & 1 of my cayuga babies was dead. he was hatvched june 3. The other 3 seem to be fine but he ws next to the bowl dead. yes the bowl wasw dirty but what duck bowl isnt when you have been at work for the past 5 hours. Plenty of food & water & others are ok. any idea? I feel so bad & I really like those guys. we now only have 1 left & 2 rouens. Thank you
