okay- let me start by saying I know all the rules about not helping in the hatch. This year I have hatched out about 300 eggs, both quail and chickens for family and neighbors, and myself. I have a 97% hatch rate. But this is MY hatch, these chickens are for me only, and of course I'm having issues. I kept my temp and humidity the same as always, but its been cold here, even getting snow- which we NEVER get. and its been HOT, and its been rainy. maybe that has something to do with it. anyway, I had 42 eggs in the bator (like a cabinet bator, really big, .. ) 2 went bad- REAL bad, I threw them out. I have had 16 hatch. The first one to pip and zip was found the next morning, still in his shell, He had died, even though he did have air. At that time I started realizing that there was no moisture in the eggs, and I kept it at the right humidity. The white part under the shell was just rubbery. and dry. So I shelled and pulled the white off the next 15- I'd let them pip, make sure they had an air hole, and if they wernt zipping within a few hours I'd go ahead and get them out. The actual membrane with the blood vessels would mostly stay intact on them, there was minimal bleeding, they would lay until they absorbed the rest and all are up and going now. I have tried to 'listen' to the remaining eggs, yesterday evening, 3 for sure had loud chirping and some tapping. They are STILL not pipped. this is pert near 24 hours later and I dont want to loose them. I guess my question is, how long can you hear them chirping and trying to pip before they usually get the hole started? All the rest of them were born 3 days ago. I havent had one hatch out since saturday night, and this is Tuesday. I am down to 5 chickens in my yard, and I really need as many of these as possible. And since next month I'm getting my kids 4-H project cornish cross's I really dont want to have too many chicks running and around at the same time and dealing with all of them. SO it would be a few more months before I could hatch more. This just makes me SOOOO mad- The only problem I've had with eggs not hatching is just dud eggs. once in a while I've had to help one or two out, but I credited it to shells that were too hard, or just alot of the white stuff on that certain egg, but this batch its been the WHOLE one. not a one would have made it out.
