I have a poor pullet that I am sure has Mareks. She is fully quarantined from my flock, but she is going downhill fast and having trouble holding herself upright. I don't want her to suffer. I don't think I can decapitate her. I am new to chicken husbandry and not quite up to that yet. Anyone have any ideas? I will take her to the vet to be euthanized if necessary. Was kind of hoping to keep her here at home then bury her. Thank-you for all your suggestions but I have no experience euthanizing a pet so I was afraid I'd bungle it and cause more discomfort for her. I caved in and went to our vet who was wonderful and very kind as always. It's hard to find veins on poultry (especially when you don't treat poultry) so he was able to give her an injection that included a sedative so she was not uncomfortable. I am SO angry at the man that sold me this bird. I feel so bad for her, at least I have the knowledge that I treated her for 2 weeks and attempted everything I could to save her. The vet also felt it was mereks he did an evaluation before he put her down. Poor sweet Stacia. At least she isn't suffering.
