I have two small, hairy, hardy ponies. Ex feral ponies. Neither are in work. They are usually out all summer and in during the winter (mostly to save the ground). Last winter I noticed they were scratching a lot in the stable, sometimes even drawing blood. Vet confirmed no parasites. This winter I am pregnant so they are out so far. They seem way happier. They're getting haylage and are holding weight, they might even be in a bit too good condition. Is it ok to leave them out all winter even though the field is now getting very mucky and wet and has no grass whatsoever? We are not worried about saving the field as this year the ponies will be moving in the spring and we plan to plough and reseed.
