i have 4 sweet grass that have grown up very healthy this year. I noticed 2 days ago that they were starting to get yellow lumps on their caruncles. Today the lumps aren't as yellow but are getting black scabs on them. [/IMG][/IMG][/IMG] Does anyone know what these are? I have several other turkeys but the bumps are only on these 4. They all hatched together and spend their days together. Did they maybe get stung by something?
