You'll get lots of different thoughts on your last question and they are likely all correct. You'll need to find what works best for you and the girls. Personally, mine get breakfast at about 9 and get let out of their shelters. I chose that time in an effort to get eggs before they are let out... They get dinner about 5 (an effort to entice them to return to the protection of their electric fence and get ready for bed) and then go to bed and get locked up at dusk. Mine live on pasture with an electric fence, but they go where they wish during the day. I have a large flock and I do lose some to predators, but not too many. I've only got five of one of my rarest breeds and they are on permanent lock down until I can get that number up to 30 or more.
