My Buff Orpington hen, Rose has been setting for several weeks now. She started out with 4 eggs, but the other hens kept "giving" her more eggs & she wound up with 15! She is only about a year old, so this is her first time being broody. She has not figured it out yet & has broken about 4 or 5 eggs & half of the time, she will push some of the eggs out of the box & only sit on a few. Well, finally a baby hatched 2 days ago and one is pipping now! While checking on the chick & the pipping chick, I noticed that one egg had a huge section cracked off of one end! It is about the size of a nickel, but the membrane is not punctured. I am afraid to put it under Rose because she has been so rough with her eggs & the other hens keep getting in her box & they push the eggs around. I am afraid they will puncture the membrane or break the egg more. I can see the chick through the membrane, it is moving & appears very close to being fully developed. I can see its head & its beak. I do not think it is ready to come out because I can see a little bit of blood. What in the world can I do? I do not have an incubator & being Sunday, my feed store is closed or I would go buy one right now! Right now, I have the egg in a plastic storage tote with a lamp over it (the lamp I used for my baby chicks). Then, I covered part of the tote with a metal cookie sheet to keep some of the heat in. Also, I put a jar of water in for some humidity, but I think I am going to swap out for a tray of water with a sponge in it. Will this work as a incuabtor for now? I do have an old aquarium in my storage shed & I thought about getting that out & using it, or would a cooler work better? I would really appreciate any advice or ideas. I want this egg to make it!
