For the coop I'm going to build a frame, cover it with plywood and paint it with water proof paint. It will be 6 feet wide, 4 feet tall, and 4 feet deep. I will mount 2 thick dowls to hold the 2 plastic bin's that will be nest's that I can remove via the roof... that will be set on an angle with 2 hinges on the front of the coop so I can stand behind it, lift and clean or harvest the egg's. The door for the hen's I want to have an easy way to close off so I'm still working on that. The run will be 6 feet wide to meet up to the coop, about 12 feet long, and 4 feet tall. I plan on building a frame and then creating the same type of lid action for the run as the coop for easy cleaning and food and water refilling. Will this be adequate for a max of 4 hen's (if all 4 of my chicks turn out to be female)? Oh and we live in a zone 9/10 in central coast california so I'm not too worried about insulation but if I should be please let me know. I plan on drilling holes on the north and south facing sides and covering them with chicken wire for ventilation as well. Wood floor, the coop will be up on cinder blocks. And any other tips would be very VERY appreciated!
