Honestly I would be checking out other barns. I am sure there are much better barns then that one especially with drainage issues and wet bedding. I bet the bugs are nasty with all that wet ground.
I don't know about the contract you have but in mine I cannot change feed without 2 week notice. I consult my boarders on any changes that are being made. The horses are my top priority but so it the care of my boarders.
Go check out other barns you find one make sure you give the barn your at 30 day notice of the move when your ready.
Good luck! TRR
