I just ordered a dozen wheaten penedesenca eggs that will go into the icubator soon. I have no expierience with mediterranean breeds but think their combs would be rather prone to frostbite up here in the north. I am in the process of designing a new coop and was thinking of building a system to prevent the frostbite. I was thinking of hanging lamps every two feet or so about 18in over the roosts. I was thinking the heat from the lamps would make it warm enough over the bird's heads to prevent frostbite. Could always add heat bulbs during the coldest times. I was also thinking about mounting a space heater to the wall next to the roosts. What do you guys think?
