My buff-orpington was pretty sick yesterday - better this morning. Sneezing, wheezing, gasping; no secretions from nose or eyes or discoloration. She has been doing the sneezing occasionally but there was a escalation yesterday and she was pretty sick by evening. I have her isolated from the other girls because they started to peck at her - I think they were getting annoyed with her constant unusual noise! She stayed pretty active through it all - they are free range - just go into the coop at night' Any advice would be appreciated!
