How long to soak hay for?

[rose bud]

I'm just wondering how long you should soak your hay for to reduce the calories in it?
Just trying a new theory that maybe if i feed the new pony (who has gone from bombproof and placid when we bought him 8 weeks ago, to spooky and like he might explode when ridden) soaked hay he will eat less of the grass that i think is contributing to the behavour. He has to live out. Any ideas?

When my horse went down with laminitis we soaked the hay for a few hours. Also it would be worth trying to get final cut hay from last year.

I soak mine for my good doer who is not very much over weight but I like to control it best I can. I soak it for about 8 hours. He gets a small un soaked net in the afternoon as a lil treat

I soak mine for between 8-12 hours.

Thankyou for the replies so far!
Does anyone find that they need to soak their horses hay as he has too much energy?
