A flat roof only needs a few inches of slope if it is properly supported to avoid sag. An unsupported flat sheet of plywood would need more slope because it will sag and trap water. I had about 6 inches on my first coop over 8 feet and it wasnt enough. The plywood sagged a lot and i had some 2x4s supporting it. Im thinking 2-3 inches per foot might be enough if you support it with some kind of rafters.
A gable roof with a standard pitch of 4/12 is 4 inches per foot. At that pitch it would have to sag a LOT :-)
You like variety too, i see. I have 2 of each for 5 breeds plus 4 turkeys and 4 other breeds for 9 breeds total. I like to look at them all running around in the run. They all seem to be getting along but i chamfered the corners in the coop and run to prevent trapping and pecking. The older hens sometimes are aggressive but no damage so far :-)
I was not prepared to raise chickens. My family just brought them home one night so i had to put together a small cardboard box for them and used shredded papers for the first few days.
I don't know much about breeds of chickens either and now that they are 8-10 weeks old i can see 3 different types out of 5. I have no clue what breed they are though
For my lot size, i'm only allowed up to 5 chickens per city's code compliance.
True :) the main problems with plywood are sagging and warping due to rain and sun exposure
but if you have support beams to screw them down.. even warped plywood is not a problem. To cut down on cost i used 2 sheets of warped plywood available at home depot. They have those lumber marked with purple paint, those are 70% off.
i have yet to see any problem but i'll keep an eye out for it. Summer is just around the corner so when the temperature hitting 110-120. when we will see
this is original structure (with 1 coat of waterproof finish)- i put in enough 2x4 on the roof to support any roofing materials i'll use plus hooks to hang the feeders as well. I'm out of money atm but i'll add a 4'x8' extension later so total dimension will be around 4'x16'x4'.
I live in the city + area with HOA.. so have to keep things within their rules/regulations.
still build you own coop is cheaper then those coops available in stores that is for sure
these are from a petsmart store near me.. $300 each for these tiny little coop
