Hi all, I am building my first coop/run for my first three hens. At least I hope the three chicks at home are all hens! We have a Rhode Island Red, Dark Brahma and a Salmon Faverolle...the latter two we specifically got for their demeanor as we have a 2.5 yr old and 9 month old at home, both will definitely interact with the hens. The RIR is 2 weeks old and the others are 1 week, at first the Brahma tried to establish herself as top dog, but the RIR has quickly made it obvious that she is Boss (which is what I named her, creative huh? ha!). The faverolle has made it obvious that she is content with being a follower. Anyways, I am looking for tips/suggestions/things you wished you thought of before you built, etc... The link below directs to the coop design I made in google sketchup. the coop is 3x4 ft and 4.5 ft tall (raised off the ground), the run is 4x10 ft including the area under the coop. I plan on sinking 2 foot 4x4 posts a foot and a half into the ground at the corners of the structure and than attaching 2x6 on edge along the entire perimeter to provide foundation/structure and to hold in whatever type of litter/fill I settle on...leaning towards sand. I will bury hardware cloth at least 1 foot deep around the edge and may bury some coated metal fencing along the run floor even with or slightly lower than the 2x6's so that it will be at least 6 inches below the surface. I am planning on having a removable coop floor of 1/2" plywood covered with vinyl. Also not shown in the model is plywood on the interior walls which I plan to paint for easy cleaning and mite prevention. I know that I could simplify the framing and make it generally less beefy, but I want to build it to last. A couple specific questions: 1) To any experienced builders, do you think the buried 4x4's at the corners are overkill? My thinking was that it would make it easier to level initially, and do a much better job of keeping it level than just setting boards in the dirt. 2) I am sure this is plenty of room for 3 hen, which is what the portland codes allow, but if I wanted to go through the permit process and add more hens, how many do you think I could add? I was thinking 5 could be comfortable with 2.4 sq ft in the coop and 8 sq ft of run per bird. Plus we plan on fencing the back yard and letting them range with supervision. Thoughts on this? Here is the coop in sketchup and an image below: http://sketchup.google.com/3dwarehouse/details?mid=7fdb0f0504a935572fb1c82846e3c881&result=4 Thanks!
