Hi all - Back from being gone awhile!! I've been working out of state for 3 months - my DH, thinking this was a good thing, mixed the hens feed 1/3 scratch, 2/3 layer mash. We do have some very large mixed breed hens, one of which has gone down on her legs - can't walk, but eats. I chalked it up to just being too large a bird. We now have 2 of my very best silkies that have done the same. I found out today about his feed mix. Do you think this could be my problem? And, what do should I feed these hens now? I found a "rickett's diet" (oats, yogurt, vitamins, calcium, etc) Advice?
