It is important to stay flexible and in the moment when training a horse. There are different methods for different horses. No one way is correct.

Often I hear opinionated horse people saying. I always do such and such. For instances using a stud chain on a horse when going into a trailer. In my opinion this usually is going against the goal of releasing pressure on the front end of the horse and increasing pressure behind the horse. This may work on a less physically sensitive horse (some warm bloods, drafts, quarter horses, etc.) and then not work at all on a very physically sensitive horse (Thoroughbred, Arabian, etc.)

Also with scheduling- While yes keeping a regulated schedule for feeding and chores helps horses feel more comfortable; sometimes if there has been a change like a new horse has entered barn  or weather is different, light is different because of daylight savings, etc. then it is best to adapt to the situation and make the best decision for the horses collectively. Like feeding extra bran mash. Moving horses to where they feel most comfortable in proximity to each other.

Bottom line, Assess in the moment and Adapt.
