Hi all friends,

I am from Lao PDR.

I have read through your all advices and will change next incubate setting chicks eggs.

I have incubated 3 time now and 80-90% of my chicken eggs not hatched. The chicks full develop with hair, but just dead few days before hatch.
My machine is a Chinese brand, I setup temperature at 99.68F and humidity at 60-70% as the manual book advices.
I feel so disappoint of my machines any where thanks all your advices, and I will try again.

Kindly regards,

Pao
