I have been reading thru lots of great posts, but so far haven't found exactly what I am looking for. My chickens live in my orchard, about a 1/4 acre which also serves as a daily dog run for 3 dogs. Our big dog lives in there at night as well. So far the two chickens have been doing great there and the only housing they have had is a small nest box with a roof that sits on cinder blocks. Our big dog has recently figured out she likes fresh eggs, so she has been eating them rather than us. I want to build a small chicken house preferably portable that will get them up off the ground where she can't get to the eggs. Also we have baby chickies in the house so our flock is going from 2 to 8. How much house do I need to build for 8 hens? I have a picture in my mind of what I want but not exactly sure how big it needs to be. It would be used strictly for sleeping and laying as my hens have a nice orchard to live in. I have a small covered dog run to put the babies in when they go out and I figured I would put the old nest box in there till they are ready to go out with the grown up hens.
