That sounds like a decent size coop! On the roost height, I wouldn't put it too high. Knowing that birds like to roost as high as they can get, I built a ladder style roost where there are roosts at 2, 4 & 6' high. Now I'm having issues with bumblefoot that I never had before because most of them roost on the highest one. So now my next job is to take it apart. I now plan to build it about 3' high and have 2-3 roosts all at the same height. On the nest boxes, the main thing is to have them lower than the roosts, because if they are higher they will just try to sleep in the nest boxes. You will probably need to cover any rafters on your coop or they will try to fly up and roost in the rafters. I stapled chicken wire along underneath mine to prevent them getting up there.I am so happy that I am going to have a nice little coop by the end of this monthIt is just an 8x12.. but that should be good enough for what I'm doing. I am going to put in a 12' roost across the entire coop (how high up should I put the roost??) and some nest boxes (how many nest boxes do I need for about 20 layers? and how high from the floor should I put the boxes?) The area under the nest boxes will be used as storage for food bins.
I usually allow 3 hours to OKC from Wichita. Since you are already a little south of Wichita, your drive time would probably be lessWhat is the drive time down to OKC, I haven't driven it enough that I just don't know.

Yeah, I wish I had thought of that when I installed my nest boxes. The bottom is about 18" from the floor and it is a 2-tier box so the top boxes are pretty high up. In addition to redoing my roosts, I will need to lower the nest boxes. Not a huge deal since they are just installed with a couple of screws into studs but a hassle to go down there and do it. It is another job that takes two because of the weight. I need someone to hold one end while I install the first screw....... You want those boxes pretty low to the ground.
Interesting. I don't think I'll try to plow through the article because I've never been strong on biology/genetics. I had just always been told it was the hen that determined gender and accepted that. Wouldn't it be cool to find the magic combination that always produces pullets?Actualy HEchicken it is my understanding that it isn't either the male or the female that determines the sex. I'ts a combination of factors and presence of DMRT1. It is hypothesized that it is caused by conceived functional interaction between the W and Z sex chromosomes.
Chickens and other fowl are still being studied, and they are totally different than what we normally know about genetics. There are many influencing factors that cause one sex or another the way I understand it. If you are into biology, here is a link to an excellent paper about it. http://faculty.weber.edu/rmeyers/chicken sex determ.pdf
I've read tons of this stuff cause there is so many disagreements to it. I believe it falls into that category of out of our normal school of thought so we have trouble understanding how it actually works.
Whatever the clue is I do know I have certain roosters that produce more of one sex than another. Not sure what the correlation in the puzzle is but it certainly in my best interest to change roosters and hope for a better outcome. To me it seems like any other genetics. If you end up with undesirable results you cull and replace with better ones.
Well, we are training Tory to the invisible fence and so far it is going okay although I think she's a little traumatized, poor thing. I've never done this before so for those of you who have, feel free to jump in and give any tips you might have. I *thought* it would give a warning beep and that would be followed by the shock if she didn't turn back but in reality it seems to give the beep and then almost immediately shock so she doesn't have much ability to retreat after the warning. DH says what he read is that the only way to change that is a magnet on the collar (kind of like the pullet shut door can be programmed by a magnet) but we don't have a manual saying how to use the magnet on the collar to get the desired setting. Grrr. Last night I tried having her on leash and walking her slowly to the fence. My thought was that when I heard the beep, I would yell "No" and pull her back before she was shocked, to give her the idea that the beep means retreat. However even though we walked slowly, when I heard the beep, my yell and pull was simultaneous with her getting shocked. She yelped and ran back toward me (at least she didn't go the wrong way). We put her on the tether last night because we didn't want her blundering around getting shocked all night - we want to be there with her to help her understand it. This morning I let her get too close to another perimeter and when it shocked her, she yelped and ran back in, looking back to see what bit her. She didn't seem too upset after that, and continued playing with the other dogs in the safe zone. But later she snuck off to try and go up to our neighbors. DH hid around the corner and watched and when she was shocked, stepped out and called her to him. She came running and then went behind my chair on the porch and didn't venture out for at least 20 minutes. I think she is starting to see the porch as a safe zone and the whole yard seems to be booby-trapped to her.
After morning coffee, my dad and I decided to try to work some more on putting together a dog run I bought on CL and to get there we had to cross the line. I told Tory to stay but she doesn't understand the stay command too well and tried to follow. This time when she was shocked, she ran through it and out into our pasture. She was in a kind of panicked lope - perhaps scared that whatever bit her was chasing her. I was running as fast as I could to get it turned off so I could get her back on the right side of it. I watched her turn and start back towards the house and I think I got it turned off just in the nick of time so she could cross back over the line without being shocked on the way back in. She kept running back to the front porch and has stayed in its vicinity ever since. I feel so bad for her as I'm sure its very confusing. But I don't know any other way to teach her and she does have to learn it. The first few weeks we had her, we didn't see any sign of kleptomania. But this week 4 different dog toys have suddenly appeared in our yard. I know exactly where she is getting them - one was even labeled with our neighbor's name on it - so I can return them but I'm sure they're just a tad annoyed to not only have our dog visit theirs regularly but now steal her toys as well so.....it has to stop.
