Desert Urban Coop

Here is my urban coop. I built it with plenty of ventalation for the Arizona heat. There are two doors, one to get into the coop and one to get into the roost. The chickens seem to really like it. The nesting box was built on the roost door and opens up aswell. You can see that there is the PVC feeder and waterer with two nipples. The waterer holds three gallons. I also have a quart waterer hanging on the right side.
We had a monsoon rain last week and the chickens did really well.

 

Thank you. It was really fun to build. I learnt a lot that being my first coop. Now, Im really looking forward to building the next one!
The one thing that I learnt was to use good wire. I tried the 2x3 welded wire, but the young chickens can almost get out. Then I had to buy poultry or hardware cloth for the bottom section. For the coop area, I ended up using 1x2 welded wire. It was more money, but I think that it is well worth it in the long run.

 

I have a roost question for everyone. This is the first time that I have had chickens. I built the run first, then added the roost on the left side of the picture about a month later. My youngest chicks go up to the roost everynight, but the older ones that lived in the coop for several months want to roost on the ground or in a plastic box that I cut a semi-circle hole into. For the last few nights, I have been picking up the older hens to put them into the roost. How long will it take for them to learn that they need to go in there at night? Any tips???
