Ok, mine is simple and relatively inexpensive. I haven't finished the run yet, but when I do I will have about $450 in the whole set up. It is also relatively easy to build, and while it is not as fancy as some on this site, it's not too bad looking
Right now we are going simple and cheap. We are in the middle of building our house( we are doing it ourselves) .This has only cost about $120.00. I have plenty of scrap wood to build a house for the inside. We are only going to put in 6 cornish bantams. Then after we are finished with the house we will expand. We have ten acres to play on.
