So I noticed yesterday that my khaki drake is a bit off. I was digging in the compost pile to add to my garden beds and usually my ducks are right there 'helping' but the drake just hung back. He was still acting normally otherwise drinking and pushing the girls around so I didn't worry too much. This morning he didn't eat before going out and didn't hop in the pool with his girls and when offered banana (his favorite) he got excited and ran for it, but didn't eat any. Any thoughts or suggestions?
