I have a 3 1/2 month old filly.... mom has been separated off and on for anywhere from 8 - 10 hours at a time because she is in heat and in with a stallion. I keep the foal separated so we don't have any problems. The foal (Destiny) 'hangs' with Aunt Breeze (my maiden mare) in the pasture and the first couple of day she was upset and trying to hang with mom by the fence, but now seems to be pretty happy away and out in the pasture. Seems to be a good time to wean? She eats grain and has pasture 12/7.... HOw long will it take to completely wean her (?) and do I just keep mom and her completely separted for how long?
