So cute! Are they doing well under there? So glad you shared your pictures of those little cuties! I've never had Silkies, although they were recommended for the grandkids as friendly and that they liked attention. I just didn't think they'd meet what I needed my chickens for, but that doesn't mean they don't make me smile when I see pictures of them! The pad seems a little high, but if they are 10 days old that may be just fine! If they do seem to be a little chilly, you can close off the back a bit to hold in some heat, and maybe drop the pad a bit so it's closer to their backs. But it looks as though they are doing very well, so if ain't broke, don't fix it!! Keep us updated on how they do....they are adorable!
