You're right, can be really hard to know what's ailing them.In more ways than one... I did the routine worming but didn't do the corid treatment, the stools look fine but I will know if it is worms or cocci today. The other birds that came with him are all fine, they were picking on him too.
I don't mean to hijack your thread, just making an observation that sometimes it can be really hard to know what the problems are.
