hi, omg you have a summerhouse how blooming posh are you!!
I think maybe your doggy wants to keep the piggys warm??
I think they should be fine as long as you fill it with loads of hay! Is there anyway you can cover it up more though, like have fleece on top? Just for extra warmth?
Yes I could do that or even wrap the pen in silver bubble wrap stuff and a roof.... that would be warmer wouldn't it? Thanks - you got me thinking.
