I noticed this afternoon that he was kind of lethargic and when I took food out he didn't eat. I got him up and moving. When he laid back down he was breathing funny (seemed like he was taking really deep breaths). Then I brought there favorite snack out watermelon and he are that and drank a bunch of water. Took a bath. So I thought maybe it was a fluke. Then tonight my other 3 were out playing and he is just laying in the duck house.he stood up but didn't run. He let us pet him (not normal) No nose drainage no eye problems. He looks fine. Just acts off. Any ideas?
