My BO sent me an e-mail asking if we wanted to put the horses on some rice bran to beef them up for the winter. 2 weeks ago when I saw them, they both were in great shape and a bit on the chunky side (though I really expected that since they've been out of work for so long)
Last year neither of them needed a blanket and were both of good weight going into winter and coming out.
We do have winter blankets for both of them if they didn't grow as nice of a coat or were a bit thin going into winter.. and we can always add the rice bran then too.
I don't plan on working them until, the earliest Spring 2010, but that depends on how I am dealing with having a newborn.
