Ok, I got a bug in my bonnet today, after watching my five year old daughter chase a 5 week old chicken all over the back porch, christening all things in its poopy path. She had opened the brooder to hand feed the girls, and Dr. Henny Henny flew out. As a matter of fact, all of them are trying to fly out of the brooder when the top is removed. They are 5 weeks old, mostly all feathered out. 8 are completely so, while one Maran still has mostly pin feathers on her back and one small EE has all back feathers but breast feathers are not yet meeting in the middle, even though she is the same age. I went to Ace hardware and bought a light bulb holder with a clamp. I have a Catawba Coop tractor ark, so the roosting area is very small...only about 18 inches high. I cannot hang a standard heat lamp. Of course, Ace only had 25 watt red bulbs in stock, not 40 watt. It's going down to a low of 53 in the am. Do I chance it tonight with the 25 watt bulb or wait until I get a 40 watt, or wait for tomorrow nights low of 55 degrees? No rain in sight for 10 days, so now is just a great time otherwise. Just in case all of you are wondering how I will keep 10 chickens in a Catawba Coop, I'm not. One is a roo and I'm only keeping 4 + 1 bantam. The other 4 are going to my mom's coop.
