This is my favourite Light Sussex hen Daisy. She has been off lay since October and around the same time her comb became very dry and much paler than usual. Over the last couple of weeks she has also had some patches of dried blood and scabs on her face. She has been treated for mites. She is still eating, drinking and behaving as normal (she's the boss) but it looks unsightly and I'm worried that something else is causing it. In these pictures she has been living inside for 2 days and I have cleaned her face and rubbed some coconut oil into the dry skin. Any advice appreciated!
