Hey - my light Brahma had bubbles in her eyes (bilaterally) this morning. Caused her to shake her head, and generally stumble around a bit. I did some research and think its MG, separated her, put antibiotics in her water, and will clean all other waterers soon... My questions are these 1) how long should I giver her antibiotics and keep her isolated? 2) do I need to treat the rest of out flock prophylacticly? Thanks for any advice!
