I had a nest raided by a rat and the nest mate killed and part eaten. The one who survived was abandoned by the parents and is blind in one eye from the rat attack. I've been feeding it with thawed frozen peas but it isn't making any effort to start feeding itself. Is it that it can't focus on the feed or I wonder has something else happened? It's now undersized compared to batches of other youngsters hatched at the same time. They're all now pecking at feed and making small flights. This half blind chap isn't doing anything. Any thoughts anyone?
