Here is my situation: I board my horses by renting a small pasture and barn, and my chickens live there, too. There is another boarder with a pony that lives with our horses and she got some chicks for her kids last Easter when she saw my chickens. The issue is that since the chicks came to live at the barn (almost a year now) she has never bought them food, or equipment such as waterers, or even a coop. They are living in one of the horse stalls and using my equipment and eating my feed. Yesterday she tells me she wants more chickens. Smh. I’m not good at confrontation, but this is getting irritating. What is the best way to approach her about taking care of her own birds?
