Also, another thing I have found varying information about is them having a puffy neck. It’s on the right side of the chest/ neck area so I’m pretty sure that’s their crop. They have access to food 24/7 because I saw that people recommend letting the ducklings feed themselves as much as they need. The little one has always been a bit puffier in the chest, but 2 nights ago I saw that both seemed a lot puffier than normal. It feels normal (squishy, fluffy, fatty, nothing hard). The first night I took food away that night to see if the puffiness went down by the morning and it did a bit. Same thing yesterday/ last night, but I did not withhold food last night. Just trying to figure out if this is just normal digestion because they are eating a lot all day. Or if there’s a point where it could be a problem to have that fullness all the time?
