My 3 month poult has a tumor on her upper eyelid about the size of large pea. It has grown quickly, over only the last week or so, she is very tame and well handled so I know it did not start sooner than this. Is this common? I know it is a cyst or tumor as the other turkeys pecked it and I thought it was an absess, but when I went treat and drain it all I found was tissue and no puss. Any suggestions?
