Evening feeding of equines

Evening feeding of 22 equines takes about an hour after fully trained. We feed around 4:00 or so depending on the time of year and daylight. It’s good to be finished before dark. It’s mostly hay that we feed at night though a few have pans of already prepared feed that we give to them. We are very organized and you would be fully trained. 
Currently, we have a need in our schedule for Thursday and Saturday evening. One or both evenings are available. 
Horse experience is wonderful but it isn’t necessary. A general experience in the care and feeding of animals is helpful.
