We had one just like that and I had to let my husband cull it a few days ago The poor thing was using all its energy to try and eat and while it was still growing (however very slow), the crossbeak was getting much worse and as of that day, the other chicks were starting to peck at it's exposed tongue!!!! That was horrible and as soon as I saw that I knew That was it. Especially since it was so young, and it had gotten so bad so fast. I'm sorry....this is the tough part of raising animals.what the crossbeak looks like today. . ..she's thinnish, but still active eating and I try to isolate her to and feed her stuff she can scoop up. But I do not have much hope of her doing well in the long run. I know I should put her down, but I will take her to the vet for that, I just can't do it myself. =( I'm a coward, yes. She got some scrambled eggs yesterday and she ate some, she refuses to eat from my hand or allowing me to 'help' her at all. I don't think any amount of trimming or supplements are going to help her, it's not a little crossed, it's majorly crossed.
