After about a month, we were able to move the girls in Saturday night and they've been doing good. Hoping tonight they will go in by themselves when it starts to get dark.
You might consider leaving them inside their house for a few days to get used to it. They will learn that this is "home" and will be more likely to put themselves to bed.
I also only feed treats in the coop. That way, when I call them, they come running. Very convenient for when I have to leave and don't want to leave them free ranging.
Initally it wasn't too stable with cross-wind or pushing, so that's why I made the kick stand out of 4x4's with a 2x4 base and spread the rear axles to full 3'.
I designed it using photos of other coops and ideas from several things. I put in a removable floor so it could be hardware wire during the summer, then a sheet of plywood in the winter.
I used wheels off a Harborfreight (HF) 1000-lb garden cart, but the rear axle i had to make. The frame is treated 2"x4"s that have been ripped to 2"x2" because they cost the same as 2x2 here. No good sources for recycled wood that I was aware of so I had to buy new lumber. The siding is rough cut cedar and has been sealed with bher fence finish.
Right now it's got a HF solar powered light, but I don't need to much lights. I haven't tabulated the cost, but it was cheaper than premades but more than I would have liked. I guestimate about 600-700$ after everything. I could have saved some money by using waferboard, or plywood, but hey the wife doesn't ask for much, and so I figured I would make something no one could complain about.
