Hi guys! First post ever, joined for your expert opinion on current boarding situation. Situation is 3flakes of hay, no matter what condition, training and/or age horses is, given only at night. Turned-out daily with round hay bale and lots of other horses. Poor pasture no green and all mud. I am now supplying my own hay in addition to their 3 flakes to ensure my horse has all he wants throughout the night. I also added another bucket of water! This is only day 2 and they have already complained that the left over hay is just a mess in the stall. As if poo and pee are not messy!! Left over hay amount is minimal. So what would you do? If intervention was not done my horse would continue to lose weight!

For now use a net to minimize waste.
Your already unhappy-start looking for a new barn.

Three flakes is actually a nice hefty feeding. If they are finding a ton of left over hay the next morning, yes it does make the stall very difficult to clean out. Of he is leaving hay and they are picking it out in the morning you are just wasting it anyways
