My hen had 10 eggs under her and she hatch 6 and she's not laying on the 4 any more and they only have 4 to 7 days to hatch how do I keep the warm so they don't die
You may be able to put a shoe box or something inside a tote box, put the heating pad under the shoe box. Put a towel or something in the box to keep the eggs safe. You also need some humidity in there maybe you could use some small bowls of water. If you put uncooked rice into old socks, and microwave them for 30 seconds at a time they will hold heat too.
No I do not think so, I would set them around the box, but not touching the eggs. A styrofoam cooler would be great too, they have them at the Dollar Tree. You need to keep the temp about 100 and the humidity about 50%.
