My girls have started to lay. They r all 26 wks. First day one egg, next none. We went along like that for about 2 1/2 wks. Yesterday 5 eggs! Today, 2 soft shelled broken eggs. What could this mean? They have been on laying feed for 2 months and of course get fresh everything daily. The nights here have been in the mid 40's and low 50's. Is it time for a heat source at night?
