@chickadoodles We got 4 kits, but I haven't really gotten any pics of them since it's pretty cold out and we're just letting them stay warm in the nest. Took them 4-5 days to develop fur with this cold weather, and now at about a week they've over doubled in size.
We've got the roof rails all around the house, but it's a steel roof so it isn't much of a problem. If we get another monster load of snow I might look into dropping some of it off, but right now, with only about a foot on the roof it's keeping it insulated nicely. Before the snow, the attic was about 7F warmer than the outside air, now its about 15F warmer.
