As someone who has boarded at co-op barns for 20 years, not being at a “full service” barn has its pros and cons. The cons include not having an experienced person there to meet the farrier and vet. It also means that when emergencies happen, it’s up to the horse owners to take on the responsibility.
I completely understand the benefits to the co-op or small barn set up, but for someone who travels, it can be a problem. I broke my ankle 7 weeks ago and had to move my horse to a full service barn because I can’t do the work and I would be useless in an emergency. This type of situation really only works when you have a knowledgeable person close to the barn and able to deal with the inevitable problems that arise.
