This is our first time hatching chicks, and I had 2 broodys to help me! I put 4 eggs under one, 3 under the other . Both were perfect broody momma's. 2 chicks hatched under each hen 2 days early. One hen abandoned her last egg yesterday to show the ways of the chicken world to her chicks (thus all housework has stopped to watch...). So, I put that egg under the other hen who continues to sit on the remaining eggs, only getting up to poop and eat a little bit. I candled very quickly a couple of days ago just to make sure none were clear as I hadn't done that before. All eggs have very distinct air cells (or whatever you call it) and the rest was dark. I saw no movement, but I only took a few seconds per egg, scared of doing something wrong. The remaining "sitter" sits up higher - and I often can see the eggs as she keep them toward the front, making me think they aren't warm enough. I think it is to allow her chicks to get under her. It is now day 23 - should I keep letting her sit on them. I would be so thrilled if one or two more hatched. Does she know? Unfortunately, the ones I really wanted to hatch are the ones that haven't so far , but I am thrilled to get 4 fuzzy butts that are so cute I can hardly stand it! Thank goodness for digital!!!
