It seems to me as though you did all you could. I kept beating myself up over her death also, but I also did all I was able to and without a vet in my area. The closest was 3 hours away, but now!! I did find 1 about 30 minutes away, but it is to late for sure. Someone also suggested to me that Timmi may have eaten something toxic and I did have some lettuce in the pen and maybe it did go bad and she ate it or she had an impacted crop. But she was not foaming or anything coming out of her beak or nostrils. So I do not know what happened to her. I know you are probably feeling helpless now, but you did do all you can. I also was told to separate the birds incase she was contagious, but that was not an option for my 2. They were always together, wherever Teddy was, so was Timmi or vice versa. So that is why I left him with her until she died also, and I figured, if he got what she had, oh well, I guess he will die and still be with her. When she did pass, my husband laid her inside the pen on a towel until he was able to bury her and after he took her out of the pen, Teddy kept looking for her and he kept laying in that same exact spot she laid. He was pitiful, and I felt sorry for him. He was so lonely, so I got him a new girlfriend, Tara. But now I do not have any. Because of some neighbors and my worrying about them 24/7, it was the best thing I was able to do in all fairness to the birds. When I move to another home with some acreage, I will get more, but I live in a small sub-division and there was not enough room for them. They are now on a farm with chickens.
