Today our little roo (4 months old) had a patch of feathers on the side of his neck that looked like they had dried in blood on them. I picked him up and looked closer and saw this big pink bump on the side of his neck, about the size of a nickel and standing out. At the base of is were some smaller red bumps looking just like the bigger one. The big one had obviously burst and had something like a wide crater in it. No visible drainage now, it looked quite dried up in the crater but not very healthy black color.... What is this, a cyst of some sort? Can I fix it? Does it need to be cut off? Will there be more? Is he going to be OK? I haven't touched it yet, and unless someone tells me otherwise I guess I will try to clean it and put antibiotic ointment on it and hope for the best. The roo seems very healthy otherwise, clear eyes, shiny clean feathers (except where they were bloodied), nice skin and acting his normal self. Help?
