Hello! First time hatcher here. My Easter Egger was on 6 eggs, and it appears that last night (Day 21) she killed 3 chicks as each pipped. This morning I rescued 3 eggs, and brought them inside to an emergency makeshift incubator--A cardboard box with a wet washcloth, a heating pad underneath, a heat lamp above, and a mug of boiling water to produce some moisture (and some plastic wrap over the back half of the box). Minutes after coming inside, a beak broke through a shell. The chick pecked at the hole and cheeped for about 10 minutes, making a hole about the size of a pencil eraser. It went suddenly still and silent, and hasn't moved in about 7 hours, or made a sound. I'm fairly certain the humidity level isn't nearly high enough, but don't know how to create humidity in this makeshift cardboard box. It looks like the membrane is pretty dry. We're keeping the temp right around 100. The other two eggs haven't shown any indications of movement. Anyone have suggestions? I know I need to be patient and that it can take a day or more for the chick to emerge. Should I be concerned that it hasn't moved or made sound in 7 hours? How do I know when the chick with the drying membrane needs assistance? Any advice would be wonderful. I'll have an incubator ready to go next time! Thank you!
