Hello, Im concerned about a high number of House Fiches coming to my feeders with large eye tumors and diseases. I remember seeing one about a year ago, and now ive seen about 3 individuals with the desease. Ive acctually heard somewhere about some type of house finch eye disease, but I forgot where. So I was wondering if anyone had any info about it or if theres any way to stop it if its contagious to other birds. Thanks
