Feed at night for first few days. Regulate so the food goes through the crop every four hours. I feed the last meal at 11.30 p.m. If a bird is sick, feed at 3 a.m .Start with an comparitively empty crop in the morning - leave from 11 p.m. to 7 a.m. this is all right. Most common setback is a slow crop when something must be done.
Food sits there and goes bad.
Give gastrolyte or glucose or molasses in water. Check in 2 hours. Try again in 4 hours. Weaning is the worst time. I would rather feed a one day old bird than an eight week one.
