If halters get caught on an object, it can cause serious injury or death. Dry weather may make it necessary to feed foals hay as well as grain earlier than normal. It's better to feed hay in racks off the ground. But make racks a safe height for foals to safely eat. Don't forget that foals also need trace-mineralized salt and a clean, fresh supply of water.
Loose salt is better for horses than block salt.
But block salt is better than no salt. Foals should be eating high-quality grain before weaning. If not previously creep-fed, they need to learn to eat grain before weaning. Feed a high-quality grain mix that meets the nutritional need of growing foals for at least three to four weeks before weaning. Previously dewormed foals should be kept on schedule.
