Hello BYC community! This is my first post! In the spring I plan on having 5-7 standard sized chickens! At first it became an idea to have a steady supply of eggs; and now it's become an obsession & I'm starting to see them more as pets!!! I cannot wait to have them!!! I've been wrestling with coop plans everyday but ultimately it comes down to practicality & function for the area. The coop will have a footprint of 6 ft x 4 ft. The roof will be slanted like a lean to (4ft at its highest & 3 ft at its lowest). The coop will be raised a foot off the ground, and the roof will hinge at the top for coop access. I am unable to make a walk in chicken fortress at this time...darnit! My concern is that I live in NE Pennsylvania and want to provide adequate ventilation without creating a huge draft in the winter. Average winter day has been 15-30 degrees. So far I've planned for: 1) two (12" by 18") windows that are able to open half way for additional ventilation on summer/warm winter days 2) two 4" by 18" vents with wood&hinge so that they can be propped fully open or slanted partially. Is this enough ventilation? Is this overkill? Will two windows on this structure make them too cold in the winter even when they're closed? I don't want any permanent ventilation openings due to winter chills. I like how the windows can be opened/shut, and how the vents can be adjusted to completely open/cracked open. Plus there's two so I can either have one or both open! Considering insulation, but not a heating lamp. (BF is big on fire hazards...) Any suggestions or comments please let me know! I want to do this right! Construction isn't until December so I've got plenty of time to stew on the right designs!
