Jumbo Pekin 1 yr old female. Started getting brown spots on bill abd what looked like scabs. Put iodine on it but there didn't seem to be any injury. 3 days ago developed scabs on head and back of neck but thought my drakes were just mating her too much so I separated her from the drakes. Washed and cleaned wounds with vetericyn and neosporin. 2 days ago eye was foamy and slight redness. Washed eyes with vetericyn pink eye spray. Gave injection of Tylan 50. 1 day ago still treating, right eye covered in foamy bubbles. Continued above treatment. Today, both eyes have scabs around them, right eye filled with bubbles. Left eye starting to look red, beak covered in more scabs and pale sections. Pics attached. Any ideas on what's going on? The rest of my flock shows no signs of her condition. She's in quarantine.
