As cruel as it sounds, I had one chick with wry neck last summer and I simply culled him. Hated to do it, but I've been through that "save a chick no matter what" stage and although Scout was special and he lived well and happily, I didn't want to do it again. He suffered, I suffered, and everyone who had to listen to me worry about him suffered. I'd rather spend my time, resources, and energy on chicks who don't need hours and hours of special attention.
BUT THAT'S ME AND I GET THAT NOT EVERYONE FEELS THAT WAY. I would have ignored all advice to cull Scout. In fact, I think I
did ignore it.
Maybe I'm a coward and don't want to face the trials of trying to save chicks when the outcome is so uncertain. So while I admire those who do, it just ain't me.
