My 20 month old hens are all pretty much molting (some harder than others). One of them had a pin feather which had a little blood on it which now has resulted in a worse situation as the the others of course are pecking at the spot. It was moderately bloody today. Should I separate her, salve it, cover it...??? Is it normal for a pin feather to have a little blood on it when it emerges sometimes? This is their first real molt and my first batch of chickens! Any advice is appreciated. Thanks.
