Does not understand folks candling after day 18...I just leave them alone.
Wow... That was kinda passive aggressive, in a way I feel undeserving. Maybe you shouldn't comment about things you don't understand if you don't have any helpful and non-judgemental advice on an advice forum.
Just so you know I did stop candling on day 18, which I did because I saw an internal pip on one of my eggs.
Then one egg started bruising and such, and after 3 days started smelling. After eggtopsy, I discovered the membrane was way too dry and they may need assistance.
I went into a humid warm bathroom to open incubator and checked the eggs, ALL EGGS except one was dead, and the one left had been damaged by dog bumping the incubator. If I had not intervined this chick WOULD be dead.
I had to candle to help it pip as it was in malposition, and candled one time after only when I wet the membrane. Which I have to do every few hours.to see how things are progressing, so I know when I should be here for hatch.
I know I am being a little rude myself, but I have been up all night talking to the chick through the incubator to encourage her, and making sure her membrane doesn't dry out.
Do you care this much, or are you dedicated this much to your hatches, staying up all night etc.? I apologize if I have jumped to the wrong conclusion, but from your seemingly non empathetic personality, I doubt it.
