so the tarps got weighed down from all the snow last night, this morning we had to take all the tarps off, redo the whole pen with a new white one ( the dark one was blocking light for my chickens also ) we tarped all 4 sides down with new tarps also, and what a pain. it was a complete white out and we all had to completely redo the the whole set up we did just last week. winter... ugh I hate it. my girls took one look and got back onto there roosts LOL.
