Ok, tomorrow we start the coop, hopefully to be completed this weekend. I am using a shed that is 16' x 8', but will have to divide it down to either 6' x 8' or 8' x 8', which makes 48 sq. ft and 64 sq. ft, respectively, for the coop. The remainder of the shed gets turned into a greenhouse. The outdoor fenced area will be in an "L" shape around 2 sides of the shed and will be a total of 304 sq. ft. It is sandwiched between a 50' x 100' garden, and the coop/greenhouse shed. Currently, I have 5 hens. I am *almost* positive that 2 are Black sex-links and 3 are White Rocks and are 5-6 weeks old. I would really like to place an order with McMurrays for the 'rarest of rare' collection, but don't really want an additional 25 hens (26 counting the 'mystery chick'), plus a roo...but that is another issue altogether. (That Gotta-Have-More-Chickens-itus you chicken people carry is waaay contagious!!) I know that the outdoor area can accomodate a ton of birds, but I worry about the coop area. I live in South Texas and have very mild, short winters so the birds will likely not spend much time indoors. Sooo... Question #1: Does the coop square footage need to be approx. 4 sq. ft. per bird as well as the outdoor space, or do I combine the 2 square footage amounts? In this case it would be a minimum of 352 sq. ft. or a max. of 368 sq. ft. (indoor + outdoor areas). Ideally, I'd like to accomodate 15-16 birds and have the coop 6' x 8'. Is this do-able? Question #2: I read that hens need approx. 14 hrs of light a day for the best health/egg production. Is this sunlight? Artificial light? I ask because we will be re-roofing the shed with clear corrugated fiberglass panels (greenhouse side) and wonder if I should also roof the coop side with the same. Anyone???
