My dear Old English Game Bantam has been sitting on her clutch of 12 eggs for about 30 days now. I candled an egg at the beginning and it looked like there was a growing chick in there. And yes, we have a rooster. Should I give it a few more days?
You can try the 'float test' - do an on site search, but if it really is 30 days, I doubt that the eggs are viable.
