Due to a death in my family, I unfortunately let my colt & filly nurse from their respective mares for far too long. They've been seperated now for about 3-4 weeks. How long does it take for the mares milk to dry up? I let the 2 mares out with the the colt & filly yesterday and the filly went right to her mom and tried to nurse. I caught her before she latched on, so I just need to know how long the mares will produce milk after nursing stops. Thanks for any info you can provide. I'm really looking forward to letting them all out together again.
