I had 10 Perkins in my backyard and noticed one limping one day and then the next I only counted 9 a day or 2 went by and I found him down by the water unable to walk or barely move I brought him inside and have been feeding him feed with plenty of niacin in it and giving him vitamin an electrolyte water for poultry, that also has niacin in it, (thinking it’s a deficiency) he had a bald spot on the back of his head so I’m not sure if he was attacked by something or what but it has been a week now and he still isn’t able to walk. I put him in his little pool and he kicks his legs so he’s not paralyzed I’m just not sure what to do or how to help him get his strength back
