I don't remember the hatch date, but it's plenty old enough to be on it's own. Silkie. It has seemed delayed since it hatched. I'm on the third round of bringing it inside and making sure it eats and drinks and gets strong enough to go back outside. It seems to get strong when inside and I make sure it eats and drinks. It had been adopted and cared for, on several occasions, by broody hens and even the roosters. Does well when an adult is calling it to food, but when it's on it's own it seems to not eat or drink. It eats first thing in the morning and if I throw scratch, but other times just seems to sit around and not eat. I don't think I've ever seen it go to the water and drink, but it will drink if called by another chicken or if I take it to the water. The other chickens do not pick on it. Is it possible it has some sort of damage that it forgets to eat/drink or something else. My husband said maybe it's blind. I don't know how to check, but I'm pretty sure it can see out of the left eye. Right eye not so sure. But it will peck at scratch when it's doing well. It's not bouncing back as well this time. I considered putting it down a few days ago and it started to eat more on it's own. Gave vitamins by the beak yesterday and today. (have been mixing vitamins in the food at other times) Held it and the food this morning and it ate a lot.
