Hello All, I'm a new chicken mommy and we have 4 healthy 9 week old chickens and 1 9 week Buff Orpington who is still eating, drinking, and running around happily but seems sick. Her chest/ Breast area seems to be filling with fluid. I pick all my girls up every day and look them head to toe and love on them but she began looking more plump 2 days ago and its slowly progressing. It isn't her crop, I know what her crop feels like and that still fills and empty's like her sisters do. I have read threads about ascitis in chickens but they only mention this happening at the egg laying stage and we are 4 months shy of that. Please any suggestions would be greatly appreciated. I'm willing to drain her myself if this is required. Thank you all.
