It depends on how big the barn is. The barn my horse is at has 40+ horses that are still on daytime turn-out so need to be brought in as part of pm chores. Also this time of year one staff member does turn-out and stalls in the morning but needs to fill water troughs, put out field hay, does weed eating, mowing, ring drag for 3 rings, weeding gardens, mulching gardens, fixing fences, repairing jumps, seeding fields, clean up of branches and twigs from winter etc… all of this can’t be done with only a half days work.
Spring in our area tends to be the time to catch up on any damage from winter and to get the property in order so that the summer maintenance is easier. In our case the BO is also a trainer so she is riding training horses and I guess lesson horses to keep them fit so once she can teach again the horses are ready to work. Generally another staff member grooms/tacks horses hands to trainer and then cools out last horse.
Therefore 2 staff members need to be there for a majority of the day.
Having one of the boarders help with pm chores adds another risk factor as they are touching more things that the staff touches but would not touch as a boarder such as feed buckets, supplement buckets, field gates, leadlines on the other horses, blankets on the other horses. Plus the boarder is another source of bringing in the virus and now has walked all over the farm.
For a smaller barn it may work. But some smaller barns the BO is doing this on the side and still has a FT job that they are doing from home so they don’t have the time to do extra cleaning or extra chores.
For me I still would not be able to get out to the barn before 5pm M-F since I am working full time from home. Probably many boarders are in that position so there is a narrow window during the week that everyone can go to the barn which makes social distancing harder.
Plus what do you do about that person that has a 1.5 hour time slot but stays for 2 hours anyway? There will always be that one person that the rules don’t quite apply to them.
For some barns it may work but for many barns there are still a number of logistical problems.
Yes I want to go see my horse. It has been 4 weeks. I am sure I will be all loosey goosey in the saddle once I get back to riding. But this is a freaking hobby. A first world problem at its finest. Stay home and protect the staff/BO/trainer. Really it is a few months not the end of the world. Most horses won’t mind their extended vacation. Yes there are some that mentally need to work, yes there are some that physically need to stay in shape due to things like weak stifles or are being rehabbed due to an injury but the majority of them are fine just being a horse.
