Two difficult hatches. But, could be worse. I had 13 eggs hatching last weekend, and lost three. I read here where people lose all and that is heartbreaking. The two I lost at hatch- I tried to help out when it seemed they were ready and no blood, but I did get a drop of blood and waited. Neither made it. They died in the shell. One of those pipped upside down in a spot where I don't think she could get proper air. My incubator, I love,( Majic-fly10) but I need to make some kind of mesh at the bottom as it is foam. Never had this happen before. One other chick died at day two suddenly of what seems to be heart attack- went weak after I picked her up for a minute and then collapsed and died. The rest are fine. This weekend, I had 13 hatching. I was using my styrofoam still air. The first four hatched out, and then the other 9 sat for 24 hours with two pips on hatch day until the next morning. Because of last weekend, feeling that I killed two trying to assist, I decided to be hands off. I went out yesterday on day 22 and when I got home, one of the pipped eggs was out and one was dead in the shell with about an inch zipped. One other smaller Ameraucana egg had pipped and hatched. The other 6 were fully developed, and dead in shell. I candled and tried putting small air holes in the air sac as I read on here. No life, no pips. No sound coming from the egg. Some had gotten through the membrane into the air sac, and a couple never did. I am thinking it was humidity. If anyone has any other thoughts, I welcome them. I am retiring the still air now, except for using it as a warmer for chicks between brooder and incubator if I need it. I have had much more trouble with the styrofoam bator temperature and humidity and have to watch it constantly so it does not cook eggs if the room temperature varies at all. I had almost 100% success last season, mostly using my magicfly. It is disappointing to have fully formed healthy chicks not make it out in those last hours after watching over them for those three weeks and seeing them moving in the shells. I ordered bought another generic version of my magic fly and will avoid the LG now, if possible. So, my experiment of not helping was not a big success. It helps me feel better about the failures in helping, at least. There have been a few, mostly due to my lack of experience at this.
