Hind hooves lacking concavity...Barefoot people ideas please

[StoptheCavalry]

I have had my horse just over a year, he has been barefoot with no issues since at all. I moved to a new yard in October and have noticed his hind feet have less concavity than they previously did. The other barefoot horse on the yard is also lacking concavity but she has always been at this yard and is a TB transitioning to being barefoot so could be a number of causes for her. I had been told lack of copper can cause flatter feet but having been informed copper levels are fine in the fields we turn out on only other avenue would be to have haylage tested but since it comes off the same farm unlikely this will be lacking. A notable difference may be that he previously lived out and wasn't fed (he obviously had grass I wasn't starving him or anything) whereas now he has hard feed of fast fibre, small amount of baileys no4, mag ox and pro hoof.

Horse is sound in all paces on all grounds and we have some seriously stony tracks around. What other causes are there for losing concavity, he is now doing a lot more hill work and is turned out on a slope whereas before he had been on very flat ground, we have also had awful weather lots of rain, snow and ice, not sure if this could contribute.

Any ideas?

If other horses on the yard are having the same problem, then its most likely nutrition related.
Get a forage analysis done if you can, or if not look at feeding one of the forage plus balancers.

That is what I thought but was wondering if it could be at all environmental rather than nutrition related?

It's difficult because the other horse has typical tb feet although she is doing brilliantly transitioning to being barefoot she has always been flat footed so not sure she is the best comparison although does seem odd that it has changed since we are at the new yard.

As stated earlier the haylage comes from the same farm and the fields have been tested and were found to be well balanced in everything. Possibly silly question but what would be the major difference in pro hoof and a forage balancer?

I should add having googled some flat feet his feet aren't now flat as pancakes and my trimmer is happy his feet are good I was just wondering what might be causing the change and if it could be environmental?

ETA - when I say flat he is lacking concavity other than this his feet are good
