I have 18 week old bantam cochin babies and they currently live in a brooder in the dining room. I am in Arkansas and the weather has been very HOT this month. It was 114 on our porch yesterday but last night it got all the way down to 78. It is 106 today and it is only 2 in the afternoon. They have a brooder light in with them and they use it a lot. It is 78 in the house. When they do move out they will have to stay in the chicken house itself for a couple of months until they are big enough not to escape through the holes in the pen and it is a bit hotter in there but there is a ton of ventilation and I will be keeping a lot of cool water in there. The house is 12 x 12 and 12 tall. It has two windows that are both 3 x 12 and it has two vents at the roofline on the front and back. Also the door is just a frame with a 3 x 6 screen covered opening in the middle. So my question is when will the babies be old enough to handle this heat? How should I introduce them to this heat? Any advice is greatly appreciated.
