Hi there we had to euthanize one of my favourite birds today, she was fine or so I thought but I noitced her sitting her nest breathing heavy with her beak open & then when I picked her up she winced & uttered a small cry. I looked at her under belly & it was all wet, brownish in color when it is normally white she also had a rus yellow colored discharge from her rear area.Any idea;s what it could be? All my other girls are 100% but I'm scared it is something contagious & I'm going to have to cull them & that breaks my heart!
