THIS IS FOR 2 BABY PYGMIES which I am getting in the Spring. Do I use hay or straw for the bedding please ? Someone said that straw doesn't break down so it's difficult to dipose of afterwards. They also said that hay clumps up and isn't very good for bedding. I prefer to use hay as we get it by the square bales here (Scotland). I get it anyway for the hens, so it would be more convenient than straw. Also in the day time when I am out at work. Would a shed 8' x 6' be big enough. Would a daytime pen of 20' x 20' be big enough ? With movement around the garden (in stock fencing) during the afternoon and weekends. It would be very nice to have a field or something but I don't. Just a biggish garden.
