My hen left her eggs this morning on day 19. Her 'friend' hatched 3 chicks and one of them chose to go under her so I think she thinks her job is done. The 4 eggs were left for about 6 hours and were cold. I have wrapped them in a thermal jumper and am currently sat with them tied around my stomach to warm them up until I decide what to do. Just now at least one started to cheep !! I do not have an incubator or a heat lamp. Would a box with a high power torch be sufficient ? or an extremely low oven with the door open ? If they are cheeping does it mean they need to hatch soon ? Lots of questions but I am new to all this.
