I've seen more than one small square bale with a mouse butt sticking out.
The round bales I'm getting now are over 800 lbs. Have to be. I can roll the 400 lb ones around myself. These I can throw myself against with all my might and they aren't even rocking. The pick up is also starting to handle funny with 2 on. Not as bad as a pallet of coal but definitely closing in on it.
I wish I had a tractor. If I did I would probably feed rounds all winter but I'm limited to being able to get the truck out there with the snow. So far I've been lucky. But looking at the weather report I'm thinking I need to get my butt up north and get the two I've paid for soon.
