I have a broody hen sitting on 5 eggs. She left the nest today to help raise 3 recently hatched peeps. I haven't seen this hen off the nest in the last 18 days, she decided to take off on day 19. The 5 eggs were cold to the touch when I discovered them. One of them has a pip, one of them I can hear inside peeping(really cool), and I can hear all of them tapping back at me if I tap on their egg(when I hold it up to my ear). I tried to get her to sit on the eggs again but she is refusing. I do not have an incubator. What should I do? Is there a way to finish them with a heat lamp?
