GG72 It sounds like you are real close to me.
I live just 8 miles from F&F , and the Marathon Feed Store.
Golden Comets, Red Stars, and several other names of the same type of chicken are Hybrids. Lay like crazy for about 2 years and then they are worn out and usually die. Just real good egg making machines.
Rhode Island Reds are good chickens for this area.
Americauna and the EE colored egg layers are kind of seasonal layers.
I for one, am dead set against heat lamps. also for other reasons than the fire hazard.. they are expensive and burn out in a short time..
I use small milk house heaters, (ceramic heaters) they have a fan and a thermostat.. cost less than $20.oo and last for years..
I have one insulated coop and one not.
You are welcome to come check them out for ideas.
(don't look at the mess, please).
I just came in from the shop. no heat and my hands are so cold I can hardly type.
I did get the base of the feeder all done. all I have to make are the 2 end pieces. then after 24 hours for the glue to dry, I can finish assembling the rest of it.
