I get the TSC shavings for my run and the fleet farm shaving for my henhouse, also due to the size.
I've wondered about putting shavings down in the run. I get the pine shaving bales at L & M for my coop but this winter I put down straw in my run. Wasn't sure what would work best in there. Up until Novemberish I just left it bare (used to be yard until the girls showed up last spring). How do the shavings handle the snow and rain?
The last two days my hens have been exhibiting some obsessive compulsive behavior. The first nesting box had 4 brown eggs, the 2nd had two white eggs and the 3rd had two green eggs. Two days in a row! Silly chickens.
