My sweet boy I noticed ate a ton today! He's my first duck and he just got his curly feathers in. xD I don't know whether this is serious or not. It could be normal, hopefully!! His crop looks HUGE and when he was swimming his crop kinda sunk. It looked pretty funny but I'm worried!! He's making a strange quack that sounds like a pigs oink..He's being very quiet (as usual because he's a Cayuga) and sleeping a lot. I noticed hes sleeping with his head on top of his crop and not on his back like he always does. This just happened today about 4 hours ago. He seems fine..But like I said, he's my first duck so I'm a nooooob!! Any advice would be helpful! Thanks!!
