In what way was my comment unkind? It’s not hard to get a vet to test for pregnancy. If that is something the OP suspects, then it seems logical to me that they would have the mare tested. That’s all.
Not only that, it should be confirmed sooner rather than later. If she is in foal the mare will need vaccinations and feeding changes to support the foal.
Thank you for pointing that out.
I can not see the photo large enough to tell that.
I personally do not like to hang hay nets on electric fences. I would hate for a horse to get shocked while eating hay because the bag got tangled in the electric.
As pointed out the bay is not barefoot and in the photo you can see one net and only one horse eating. It would be better to have more piles of hay with no net, so as both horses can eat and one horse cannot resourse guard. On the ground is better for the horse as they need the saliva to run down their neck to help digestion.
Nets are used for 2 reasons. 1 to feed in a stable or at a float, 2 to slow the horse down so as the hay lasts longer to give them something to do. As Honey is outside with a friend that negates the need to give her something to do or to keep her in one spot.
Our horses are separated at feed time and let out afterwards. That is not always feasible in a boarding situation, that is why the more piles than horses is used.
