Progess on my chick has really improved, we have cut down on the polyvisol to two drops per day, I watched him for 2 hours and off an on throughout the day and not once did he tuck his head. I noticed he still has a little bit of a shaking going on and he still scratches his head. But NO TUCKING.... I took him outside to try and stress him a little because when he gets anixous or stressout he starts to tuck and he didn't tuck. Enjoyed eating the grass though, couldn't stay out long because of the rain but got a taste of grass.. Now at this point should I be cutting back on the Vitamin E. or Should I just give him Vitamin E only and stop the polyvisol or just keeping cutting back on the polyvisol, the plan was to cut back each week but I'm not sure if he really needs it for two more weeks.
