I have 3 silkies, 2 roo's and 1 hen. They have an enclosed pen attached to the coop, but seem to like to sleep out in the rain. Regardless of how hard it rains, they cuddle up in the corner and sleep away the night. Should I worry ?, any health concerns ?, the night time tempature in northern Vt this time of year is in the 50s to 60s. They seem to be ok in the morning, just a little soggy.
