CSNB is very easy to deal with. I had several horses with it, and it doesn't prove any problem, as long as you leave a light on somewhere for them. I always left a light on at the barn, and made sure they were in a pasture close to the barn. I had several brood mares with it, and kept them in a stall at night longer than I did for the other mommas without it, just to give the little ones a good start, and keep stress away from momma wondering where her little one was. Then I had a small pasture right up near the barn where I kept the mommas and little ones for at least a full month -- basically until momma wasn't worried when baby left her side and wandered away. By then, they had bonded and a short call from momma brought baby running back.
It doesn't hurt them at all, no additional problems, just a nuisance in making sure there is a light on so they can see at night. A small chore when you have these special appaloosas for breeding stock. What they can produce is worth any slight thing you must do to keep them happy and safe.
