let me start by saying, i work at tractor supply & every year, we end up with one duck with wry neck & ive read so much about it that i could probably write a book at this point. i brought my wry neck duck home on tuesday, according to the hatchery, he was a day old then. for the first two nights, i gave him vitamins & electrolytes in his water & feed (i made a paste with chick starter & the vitamin/electrolyte enhanced water). yesterday, i switched him over to a formula, due to the lack of polyvisol at my local walmart, ive started making a formula, he loves him, & it seems to have improved his strength considerably. the formula consists of soymilk, chicken & chicken broth baby food, vitamin e, niacin, & selenium. is there anything else that should be added? he seems to be improving, he doesnt spin as much unless hes excited, & he will hold his head upright to eat or drink. when hes relaxed, his head is still tilted & he still flips backwards from time to time.
