Hi, I'm Gretchen and I have a young red pullet currently sitting on eggs. The eggs aren't hers as my young hens have never been with a rooster. The eggs are blue laced red wyandotte (my rooster) and auracana or rhode island red (my older hens). I'm letting her sit on about 8 eggs and they are only about a week out from hatching. the temperatures are down in the 40's and upper 30's at night. Should I move her into a warmer pen now and risk interupting her brooding or wait till they hatch? I already have the pen prepared with thick bedding and a pair of heat lamps (the pen is 8'x8') and a thermometer. I'm getting medicated starter food today.... I let her have the eggs because I was afraid taking her first brood attept away from her would discourage from ever trying again. ...bad idea?
