My 2 boys are always on vetbed (fleece) but I am due to move house this week or next and to save time on cleaning out the boys and washing vetbeds. As might be without washing machine for a few day. I have put them on sawdust and also soft straw. But they are so HAPPY! They are chatting away to each other and skipping! This was only going to be for a short time but how happy they are I am thinking of keeping them on it! They are indoor guineas as well!
