Luckily a stable humidity isn't necessarySorry for some reason i no longer get notifications anymore.
I have started another batch, currently on day 12 and out of 19 eggs, 16 are fertile and developing!!
The temp has been easier this time and its normally quite secure around the 37.1 to 37.7 range according to my 3 thermostats in different places. I do always keep the polystyrene cover on along with 2 tea towels to keep heat in.
Humiditiy is my bug bear and hard to keep steady.
We will see how successful this next hatch is and i can conclude then what i think.

One of my now almost 8 weeks old started crowing the day before yesterday (plus chasing/pecking at two others that I assume are males), and today I got my first egg

A perfectly formed egg, and also in size (11g vs 12g om average for the ones I incubated)
