Not sure if this is the right forum, but 5 of my 6 eggs hatched under my broodie and one of my americaunas was really lethargic and couldn't hold his head up. Got him to drink and he seems to be doing well after 1 whole day of life outside the shell.
This little guy has was looks like an umbilical cord hanging from his fuzzy little butt. (kinda see it in the pic) What is it and should I let it fall off or try to remove it?
