Please help

[Gigirat]

I came home today and my three turkeys have this red rash on their head. It appears that they were bleeding. I know it’s breeding season and my husband thinks maybe they were fighting but I am not certain. If anyone can help. I can say yesterday I believe one had a cyst of sorts fall out with her poo. I cleaned it off and cut it open and it was full of puss I am so worried any information would help. I did add photos.
