I hatched out 6 silkies on Sunday - all have looked healthy until today. One of them was looking kinda lethargic, so I picked it up and gave it a little water when I noticed that it has a round area on its little butt about the size of a nickel. the center of this area has a "scab" on it (I am new to this, so forgive me for being uninformed!) The other little fuzzy butts are just that - fuzzy and they are healthy and running around. Any clues anybody??? Does it sound like this one is having a real problem??
