The mare and her filly that I got about a month ago, have been separated since a few days after I got them. The filly is 7 mos. old. I've never dealt with this before (weaning horses), so how much time needs to go by with them being separated before I can put them back together again? The mare doesn't seem to have much of a bag anymore, tho she is bred and due in the spring. At least her bag isn't as big as it was when the filly was still nursing. They've been separated about a month now. Is it safe now to let them be together now, or is it still too soon?
