If this is true it doesn’t explain why the orphan could not be fed by the breeding barn, but introduced gently to other foals and dams for socialization. If some mares do double barrel other foals, then they would do so on their neighbors broodmares foal, not just on an orphan. In which case, this is not a new or additional risk to offset the benefits of herd socialization.[/QUOTE]
Most mares are not accepting of strange foals. When a foal is young, it generally does not venture far from it’s dam. On breeding farms, young foals usually go out with their dam in private turnout for the first few weeks before being introduced into larger groups. This helps prevent a young foal from being run down by a mare before the dam can intervene on it’s behalf. At one farm I interned at, they had a foal born very small and kept it on private turnout for 3 months. They were still deciding if it was big enough to fend for itself when breeding season was over, along with my internship.
Mares are also not designed to care for two foals, so if you try to introduce another foal, you are likely to not have enough milk.
Nursemares come in because of their ability to readily produce milk as well as their temperment. Nursemares are specifically selected for their willingness to accept foals not their own. Not every mare can be a nursemare - only probably about 10% of the mare population, if that, has the temperment to be a nursemare.
A breeding farm raising a bucket baby would be very difficult as you would need more helpers and definitely more helpers with more horse knowledge. In college, the farm I interned at had myself and one other person on my shift, and a person or two on each shift to watch out for mares foaling/just foaled/issues. We worked alongside some barn workers who’s main job was to clean stalls. They knew how to lead a horse and foal and clean stalls, that was pretty much it. One guy was good enough to help an experience mare foal out.
For any problem, we were calling one of the two managers of the farm of over 300 head of horses (mares, foals, yearlings, stallions). Very difficult to properly manage a bucket baby in that scenario.
