The breeder and I are so confused with this one.. These are both chocolate orps (one light, one dark), came from the same breeder and breeding pair.. One chick is 7 weeks old, and the other is 5 weeks.. The 7 week old has a few curled feathers.. The 5 week old is nearly bald, although you can see pin feathers.. They are just coming in verrrrrrrrrrrrrrrry slowly!! I have 31, ages 2-7 weeks, and these are the only two that have "issues".. Feeding Purina non medicated chick starter, they got vitamins and electrolytes for the first week, have plenty of space.. They have access to food/water 24/7.. Pics of the bald one were taken over the past 2 weeks..
