I have an EE hen that is about 15 wks old. She Is SOOOO skinny. her eyes are sunken and there is no meat on her breast bone and her crop is completely empty. I've seen her eat. In fact just today she got ahold of a huge grasshopper. I have my girls, and one boy on complete layers feed. She's been this way for almost a week. When i seperate her from the others and offer her food she only cares about getting back in with the rest of the chickens. What do I do?? Do you think an illness could be the culpret? She has no signs of illness. No runny nose, sneezing, or coughing. Don't want her to die. What do i do?
