Hello there, i'm a new chicken mama. I have two ladies, one is a Light Brahma and one is a Buff Orpington. I ordered them from the Cackle Hatchery and got them when they were two days old. They are almost 6 month old now, and still not one egg. I built them a beautiful coop and their own individual nesting boxes with ample room and on opposite sides of the coop so they have their privacy. They're pretty much free-range and spend all day pecking and scratching on our two acres and feed themselves regularly on my garden and compost but I still feed them a mix of organic feed for laying Hens, oyster shell and "Party Mix"(which consists of corn, raisins, nuts, etc) at the end of everyday. Still not one egg. I was told that extreme heat will slow down or halt egg production, and we live in South Florida and it's August now, so the temperatures reach over 90 degrees some days with like, 100% humidity. Their coop is inside this huge enclosure that used to be used to house Iguana's (the people who lived on my property before us bred Iguanas) and it has stone on the ground with an aluminum roof, so it's always much cooler inside the enclosure. What am I missing?? Help!
