Our flock is free range and June is the worst month in the whole year as far as the flock having to stay alert, and watch for predators, and they are usually quite stressed what with hatching and raising young, watching for predators, and dealing with the roller coaster climate here this time of year. In light of that, I will sometimes give them Vitapro-B, a vit/ electrolyte mix, in their water, but it averages to about once a week, and likewise ACV in the water and sometimes Turmeric in the food. Not every day by any means, but I like to use them once in a while. Once a week, average. Just to give them a boost, in case they need it. You should never give electrolytes for a long period of time, it's not good for them.
