Answering for when me and my two lived at the same farm
everything depends on the individual situation though...
What are the practical pros and cons of keeping your horse at home?
Pro - they're close to me, no travelling or extra stress after work, just time to enjoy them and they're right there if theres breaks in bad weather to ride and do things with them. Heaps of hacking and transport readily available, where I didn't have that when I was grazing them elsewhere.
Con - Farriers don't really prioritise single horse jobs(the ones I have had, anyway), you get fitted and squeezed whenever they can and can't stick to strict schedules for shoeing.
How do you deal with going to work and leaving them unsupervised all day?
Fine, they're in the paddock... eating and sleeping, nothing really to worry about. If they were stabled or visible from the road, I'd be more concerned about having someone check them during the day. But most of the time I was there and working, my job started at 5am-8am, then had the middle of the day off until 3pm when it was back to work until 5.30pm, so not a typical eight to five job.
Holidays? Schooling/riding in the winter with no school, just a field?
Hacking all year round here, quiet roads if you feel like riding on them, and I have a sand area(less arena, more "patch") where I can school if I feel like it.
Holidays aren't a problem, just turn them out, do what I can before I go(trough cleaning, sorting and portioning hay or feed) and get horsey friends to drop in, catch and brush them whenever they can if they're rugged.
What is the biggest difficulty you came across when keeping your horse at home?
Not getting interrupted during horse-time, when I am with the horses I don't want people bringing me phone calls from the house, and visitors messing up my plans when they're think they'll just drop in
as if I don't have things to do! lol
What are the bad things about keeping your horse at home and what are the good things?
Good - close, fully under my control with grazing areas and turn out paddocks, feeding whatever I want, riding whenever I want... time spent laxing out in the horse paddock
no interfering busybodies or bossy cows to tell me what they think I should be doing.
Bad - too much time spent laxing out in the horse paddock does not get the housework done and will make you late for work
Have you ever regretted keeping your horse at home?
I've never really known anything else until this year when I had them grazing and realised how lucky I was before! lol
And finally - if keeping your horse at home was more expensive than livery and a house without land - would you still keep your horse at home or would you go for the cheaper option?
I haven't had to make that choice yet, though me and my partner are looking for rentals with land, lucky me! lol
It's a bit of a dream, but if you don't ask, you don't get! The peace of mind I get from having my horses near mightmake it worth the expense, but I guess I can't really answer that one yet.
