We have two pony mares and foals that we are needed in transport to another pasture 40 minutes away from their current pasture. The mares are both quiet and have been in the tralier a lot. The foals are almost 2 months old and partially halter broke. What is the best way to trailer with both mares and foals?
Make sure there are no hazards the foals can hurt themselves on. Make sure to bed the trailer deeply in case a baby falls. Id leave the foals loose in the trailer and tie the mares. Pull over pretty frequently to check on them.
I also suggest leaving them loose. If they have been pastured together and are comfortable with each other, you probably wouldn't even need to separate them but if they are strange to each other, then you definitely need to keep them in their own stalls. As Chick said, a stock trailer is best for that.
