Is there no way you can tweak the feeding process to have the nexium fed even 30 min before evening meals?
The nexium mini-pills are so easily eaten, that what I arranged was that a small labeled tupperware sat outside my horse’s stall. When AM shift person go there the first thing they did was feed the tupperware (it just had the nexium pills and a small handful of grain - he usually just fed it by hand like a treat).
Then he would go do the rest of the horses and dump grain for my girl last. This usually bought us about 30min between feedings. Sometimes he would start doing turn out prep before dumping my girl’s grain.
Same for PM - first fed the tupperware. Then did all the other horses, then went back and gave mine dinner.
It worked effectively for her and was minimally disruptive to our barn staff – but its dependant on what order of operations are at your place whether a modifed process like that could work.
