Alright, so after these incidents with something killing all are hens. Are only surviving one is my white crested black polish hen. She had a cold and came inside when the others started dieing, thus why she was so weak. So yesterday, my mom and dad(People I pay rent to and have the chickens for cause they've got the property) brought up how I should put in the old Ferret cage and put my hen in,there. Now me and my dad are thinking of building a two story indoor coop for her. As wide as the ferret cage, but taller, with a grate at the bottom and a sliding box for all the droppings to collect into. What do you guys think?
