I agree downychick..I am sending happy hatching thoughts to you in Alaska, Sarah, all the way from Kansas!!
It seems odd to be that we have to have an exact temp, exact humidity, and turn at exactly the same time every day. A broody hen surely doesn't eat and drink at exactly the same time. How would she monitor humidity? Lol! I think we do the best we can to try and recreate the mama hen's care, and hope for the best.
I would bet they were not fertile...
Sarah ..just go ask if she had a roo ...DO you have rooster...Cocka doodle doo
She should know what that mean ,,no matter what language she speak.
