Need a little help. We picked up an ice shanty at a good price and are converting it into a chicken coop. The measurements on the inside are 5'9'' wide by 10'3" long and 7' high. It has two windows that open but I know I need year round ventilation and am wondering how many more vents I should put in and what size? I was thinking 3 to 4 would be good and going with 6x6 or 8x8 square? I am also wondering how high off the floor I should place the nesting box? What are your thoughts about the built in storage? I think they should be removed so we have more floor space and more options for putting up a roost. The run will be 20ft by 35ft and with the coop measurements what would be the max number of chickens that we could support? we will be starting out with 4 but will surely want to get a few more in time. Also the fence will be 6ft high, are we going to have to worry about the chickens getting over the fence? We have a not so nice neighbor and would be a bit concerned about them getting into his yard and ending up shot. Thanks for the help, hope to get this done soon if it ever stops raining.
