MyHaven love the chicks. I'm jealous.
My 2cents on the hay issue. I don't use hay I use pine chips in the run when it gets boggy and hemp in the coop and nesting boxes. I was told the hemp doesn't have any nasties or problems with mould or unwanted pests.
I've been to scared to let my silkies out today because it rained all day. So I can understand anyone not wanting to get them wet. I'm a bit of a sook and worry to much.
