Sunday my duckling started acting a little weird, just out if character. I had some people in another group help me with him and it seemed he was just having an issue with emptying his crop because he didn't have any grit when he started having greens. I cut his feed intake until his crop emptied and then gradually started feeding again. Early today he started acting distressed and was making motion like he was straining to poop. I noticed his belly is a bit bloated and I can feel a few small lumps of what I think is poop. I've done epsom bath. He passes some loose stool that way. But he also poops throughout the day without having any problems. Yesterday I also started him on chick grit and not today I hear a crackling sounds moving through him. Can someone please help me figure out what is happening? Where I live vets will not treat muscovy ducks so I can't even take him anywhere
