First, more information, please! How big is the property? Are there close neighbors? Are there any zoning laws regulating poultry keeping in the neighborhood?
If it were my property, I would allow a few chickens to meet the tenant's own personal needs for eggs. The tenant would be responsible for providing safe housing, including an enclosed run. The coop and run would need to be consistent in construction details with the rental house, as well as the neighboring properties. In other words, no little coop shacks cobbled together in a residential neighborhood. The coop would have X# of sq. feet, be a walk in style, or at least 4' tall, the run would have X# of sq. feet, and be covered. Based on your tenant agreement, there would be 4 s.f. in coop and 10 s.f. in run per bird. I think I'd limit flock size to 6 birds, no rooster. The coop and run would be at least 30' away from the rental home, and would be a minimum of the same distance from any neighboring homes. The tenant would be required to keep the coop and run in good repair, and limit odors by frequent cleaning or deep litter management. You would have to reach an agreement with tenant re: free range/supervised free range time, or birds kept secured in coop/run at all times.
NO WAY WOULD I ALLOW A TENANT TO KEEP 60 BIRDS ON A RENTAL PROPERTY, UNLESS IT WAS A FARMSTEAD.
