It is time for the results of our recent incubation. We set twenty eggs on the Fourth of July. Ten were from Cuckoo Marans and the other ten were from Norfolk Grey chickens.
The eggs were due to hatch on Thursday 25th, but the first chick, a cuckoo Maran made its appearance on Wednesday.
By Thursday morning a couple more had hatched and the end of day total was five.
Friday was a busy day at the Game Fair, but we checked the eggs before we left, and ten were cheeping and staggering around the incubator.
On our return we checked again and no more had hatched. As we were now a day over the normal twenty one day incubation, we decided it was time to open up the incubator and take a look. We also transferred the hatched chicks to a Brooder pen, providing food, water and an electric hen to keep them warm
One further egg had pipped, but the other nine were still intact. I float tested* these and none seemed show any indications of containing a hatching chick. All of the eggs were returned to the incubator.
On Saturday morning no further eggs had pipped. The one egg that had pipped had cracked further but the chick was struggling. 30% stepped in and assisted the hatch. The youngster was left to dry off and recover from the exertions of hatching.
By Sunday we transferred the last check to the Brooder pen and turned off the incubator. The final total was eleven chicks; six Norfolk Greys and five Cuckoo Marans. A fifty five percent hatch rate isn't great, but it could have been a lot worse. Now we need to wait a few weeks to see how many pullets we have.
Oh, and 30% is already scouring the internet for another batch of fertile eggs!

* Float testing: If a hatching, but not yet pipped, egg is floated in warm water, the movement of the chick stirring inside the egg will jiggle the floating egg. No jiggling suggests that the egg is either infertile or the chick is dead in shell.
