I have 1 lonely egg in lockdown, it is a fertility test that is doing great! My pre-lockdown candling showed a dancing chick inside!
Based on a recent experience with a chick that did not allow the yolk to absorb before hatching - do not rush them! When they are ready, they will hatch! And if they don't hatch, that is way better than them hatching and being in pain and suffering until they have to be put out of their misery! I was so excited for my last eggs to hatch, that I was cheering them on, whistling to them, gently tapping on the bator and blinking the light on and off. The 2 eggs hatched, but one of them had not finished absorbing its yolk and had to be put down a few days later. Hardest thing I have had to do in a LONG time!
It took a bit of nerve to write that above, I don't want to discuss and I am not really a hugger, just learn from my mistake. Don't rush chick hatching. If you must watch, do it quietly and do NOT help!
I hope this post will be taken in the spirit of helpfulness it was intended and that it does not spark a "help or not help" discussion. This is just my opinion based on my experience.
Happy hatching to all! May all your eggs be fertile and all the hatchlings be healthy!
