Poopies..........
When they are at the height of growing they should be putting out some things that amaze you. As long as the really big ones are within the scenario of doing poops daily, that is good. When they are adults and they put out amazingly large things daily then you may want to look at the body fat situation and see if the adult is being feed too much. Some adults can eat too much if you let them. Also, if the adult cham is not pooping daily, but taking very large poops every couple of days, you may want to adjust the diet to help "move things along". Or make sure the cham is drinking enough. Silkworms have a lot of liquid in them. They seem to help with regularity.
What you want to avoid is constipation. With constipation the cham has to really strain to get what has built up in there out. This is a factor that can cause a rectal prolapse. Stuff dries out a bit when it stays in the cham for more than a day or two. That makes it harder to get out. Good size poops on a daily basis in young and growing chams is not normally a problem. Although they look big they are soft enough to pass without straining.
Have I really discussed poop this much today?!
