I have three chicks about 25 days old. It is about 60F during the day here in Northern California. I would really like to let the chicks out during the day. (We do on weekends and they love it!) But I am worried cats or eagles will get to them when not supervised. I have chicken wire enclosure, about 3-4 feet tall, maybe if I add bird net on top, I can leave them out all day, from 8am-6pm?
