I'm planning on over wintering them as I'm going to have lots of extra pasture and feed if the pasture gets buried in snow.  The hay prices have really dropped in my area, any striped alfalfa is only bringing $60/ton at the stack with no real demand, of course a hard winter might change those prices, but right now putting pounds on calves seems to be a better marketing option for that quality of hay.  I'd probably sell 'em this coming spring but I'd rather choose to  run 'em the following summer and sell 'em grass fat but that's a long term goal.

PC, Grassfarmer, & RSL you've got me thinkin', which is what I wanted from this post.  I would have the ability to vaccinate the calves, put in the easy wean paddles, and put them back with the cows as you suggest.  I've already have part of my meadow divided by a two wire hot fence.  I could easily put the cows & calves on opposite sides after removing the easy wean devices.

Thanks
