I have a year old Buff Orp. She has been sick about 2 weeks now. She has rapid breathing, won't eat but is drinking antibiotic fluids from the vet. No congestion, no loss of balance. But today I noticed that her eyes look strange. As in her pupils are bluish, glassy tinted. Could she be going blind? I don't know what to do as I don't want to spend tons on one chicken, but I don't want her to suffer. Any thoughts? Thanks in advance!
