I had my first hatch ever, but had some problems with unstable temps in the still air LG. The chicks were a little late, day 23. I got 6 of 12 to hatch but the last chick has some yolk on him still and he also bled while zipping. There would be a bit every time he pipped and zipped. Can he survive and is there anything I can do for him? Its seems in spite of being at day 23 he was not quite ready. I am thinking it could have been from the couple times the temps went up and down. Anyone who has had experience with a chick still having some yolk on it please let me know the outcome and if anything should be done. There is also one egg that pipped but didn't go any further. Its been about 12 hours and nothing. I think it quit. How long do you wait when this happens? Thanks!
