I am hatching for the first time....well my broody hen is at least! I don't have a rooster but got a dozen fertile eggs - supposedly laid that day. It is day 19 if day 1 is the day after I gave her the eggs.
Each day I take away the newly laid eggs so she only has the original dozen. I have some clumsy girls and find a broken egg a couple times per month (in the nesting boxes) and was upset to find a broken egg under my broody this morning. I thought she must have been upset too, she is normally very sweet and happy to move once a day so I can remove some of the 'extra' unfertilized eggs. The broken egg was not from a clumsy hen, I have a baby chick (!!!!!).
I tried to candle the eggs twice, but never saw any movement or anything any of the pictures on line show and have been mentally preparing myself for a zero chick hatch. I can't believe how over the moon excited I am! There is another egg tonight with a hole in it (I had to go see if the chick was still alive... I still can't believe it!)
Is it normal for the eggs to hatch 2 days early? I keep reading about 'lockdown' but other than my 2 attempts at candeling, I haven't messed with any of the eggs the whole time. Too worried I wiould upset momma hen and she would stop sitting on the eggs. Momma hen has been shifting eggs the whole time though... I am guessing she knows what she is doing though and I don't need to do anything different for or to her (??).
One more question - I had NO idea the current chick was hatching, how long should it take for this next one to go from having a hole in the shell to being out of the egg? At what point do I know an egg is bad and won't hatch??
