I don't ever replace eggs that quit. I just take them out and rearrange the rest that are in there.Well this morning the air cells have grown a teeny bit. And the 3 are still moving around in there (I can barely see, I guess from the chick growing!). Now I have a question, again!!! I took eggs 1 and 5 out on Monday because they were dead. I was worried about the temperature not being the same so stupid me put 2 leghorn eggs in there to fill the empty space. Well now they are growing lol. I realize they probably won't make it through the hatch. Well my question is this, egg 6 is also dead but I did not remove it as I was hoping for a recovery lol I'm dumb.... Anyways I see a blood ring and a clear round circle that seems to be getting bigger! On the inside. I know I need to remove this egg but what should I place in there to fill his space? I'm afraid to not put something in there. Grr. Why couldnt this just go smoothly? Thanks again for all the help!
