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.
