This is the first time I have been incubating eggs, so I am pretty clueless. I feel I have killed some of my chicks, but thought I post on here and see what others think.

I'll start in the beginning, so you get the full picture.

I am using a 12 egg, self turning (rolling) fan incubator, no instructions, thermometer or humidity gage with it! I have used my own thermometers from the start, just not sure how correct they are. I have put 12 eggs into it, from 3 different flocks. I have failed to top up the water at stages because I was first told I only need to top it up every 3 days, but I soon realized that this was not sufficient. Also there are two water trays and I am unsure if they both need to be topped up or not. I read somewhere that some incubators are set up to only have one full tray while incubating and both trays filled for hatching.

Anyway, to cut a long story short, 1 chick hatched early on on day 20 and two others hatched very late on day 21, since then not a single noise from the incubator. :(
In desperation I have now candled the remaining eggs, 5 have got nothing in it and 4 seem to be full and have a large airsack, but absolutely no movement. Does that mean they are all dead? I have kept them in the incubator, but wondering if there is still any hope and when you would open and/or throw them away.

I made a bit mistake in that I did not stop turning them on day 18, would that have possibly killed them? And I have seen a lot of pictures of eggs standing in egg trays with the big end up. Do they have a better chance of hatching like that? I put mine up like that for a bit, but then thought that this was wrong as in a normal nest the chicken would not be able to put them up like that. Did I kill the chick by doing this?

I could really do with some answers. I should have really thought it all through before now!

Thanks to anybody that managed to read this far and is able to help.
 
Turning the eggs past day eighteen shouldn't kill them, as long as you were gentle. It sounds like poor humidity was the problem. Wait till day 23, and if they haven't hatched yet they are dead. The four eggs with nothing in them were probably infertile. Check the rooster in the pen they came from, he is shooting blanks.
 
Thanks for that. Do you think they could have just dried out? The last two that hatched seemed very wet, while the first one was pretty dry on hatching. When candling the eggs they seem very full, so I presumed they had died recently and the humidity should have been fine then???

Also would they be moving before they peck into the airsack? If yes, then I most presume they are all dead.

I am not sure. I had to mess with the temperature a little all the way through. I suppose I should not have done that, but it always stayed within a degree or so of the recommended 37.5C, usually a little under if anything. Although this is a fan incubator, they temp seemed to be higher at the top of it, but just over 37C by the eggs. And yes, I did adjust the temp a little at hatching time, but only by half a degree or so. Should it be lower, because I could not see why, because a hen would still have the same temp?

And no particular breed. I just used eggs from people I know. I do not know much about the different breeds, mine were silkie crosses, but after candling them I realize that the rooster is no good! The others were mainly blue eggs and some white and brown cross breeds.

Another question is, there is one egg I candled which has an airsack, but no chick and the airsack is mobile. How does this happen?
 
Thanks Sally, that was really useful reading. I did go back out and was going to mark the air cell on the 4 eggs left as I was holding one it pipped! Oh dear, I didn't know what to do with myself. I did put it back in the incubator, but now I worry that it was cold/low humidity. I did put a damp kitchen towel back in with it!

I do think low humidity is a problem. I had marked two of the eggs before I held said one and they both seem to have rather large air cells.

Also would you be able to answer my previous question about the egg with the mobile air sack and no chick? I have taken it out, but I don't think it was ever handled roughly. Is there any particular reason or just one of those things?

Its a rolling air cell, or loose air cell. The inner membrane broke by rough handling at some point, this is a very common issue when you order eggs and go through the postal system though and you said you got yours from friends, perhaps there was a mishap along the way. There is a section in the article about those and I added a video as well. Not much you can do with them, but if you order shipped eggs be sure to read that section in the hatching 101 article and it will explain how, why and what you should do to attempt to have them hatch.

What is your humidity at?
