We're building our coop this week! We have 15 chickens currently ages 3 and 4 weeks. (9 buffs...one is a suspected roo. 2 supposed Ameraucanas who turned out not to be, and 4 Rhode Island Reds) Husband is set on deep litter method and also loves composting. Chickens will have a 4000 sq ft fenced in space to forage during the day with a large compost pile as well. Next year we plan to let them forage in the 4000sq ft garden during the off season. (Currently growing tomatoes). Night time coop will be located under shady oak trees (with bird netting covering coop and orchard) and chickens can roam our sunny orchard during the day. Wondering if the "open air" coop design is a good fit for our climate. (One side solid, 3 sides hardware wire, metal roof with overhang. )April thru November ranges from 70s-105 degrees during the day with 40-65 degrees at night. December -March is 40's-70's during the day with 20's-50's at night. Dec-Feb have potential night time temps in the 20s for a week or less at a time. It does not snow. It barely even rains. (So sad). Hottest months are July and August and can reach 110 around 4pm if we're being honest. We get a nice breeze most evenings and nights usually cool off in the summer. Humidity is low. Want to make sure an open air design is right for us and also curious about coop size if chickens have 4000sq ft of space to roam during the day. Thanks so much! Any advice, comments, criticisms are welcome. Photos show shaded area for coop and part of orchard.
