Well it's a no go on our baby chicks. Candled all of them today and none are viable or even looked fertile to any extent (after almost 2 weeks of being sat on between the 2 hens). We do on occasion get a fertile egg so it was possible... but I guess it was more of a hormonal change for the chickens themselves as previously mentioned.
That stinks.

What do you mean you get a fertile egg "on occasion"?
Broodyness is definitely hormonal. But if you have a rooster in with your hens, I would expect most of your eggs to be fertilized.
