We are experiencing unusually cold weather here in central Florida. It is 9 am and the temp is 28 degrees. A batch of eggs began hatching yesterday. The nest box is separate from the main box. It is "portable" and so I brought it in the house last night and put it on the dining room...
The humidity always goes up when chicks hatch. My incubator glass got foggy from the hatching chicks and everything was fine...all hatched. Went up to about 75-80%.
