I have my first broody hen. She started sitting almost three weeks ago. We tried to candle the eggs around what we thought was day 7 and didn't see anything (I don't think it was dark enough when I did it. Then we tried again today when the hen got up to eat. She's sitting on eggs that are white, tan, brown, green, and blue. The white eggs I assume are no good because we saw nothing. The one tan egg had a "yolk-ish" looking area that moved to the top of the egg whenever I turned it. The brown, blue, and other tan we couldn't tell what was going on, and the green might as well have been black because absolutely no light showed through. Is candling really this hard? What are the chances of a hen sitting on 12 or so eggs when their is a very active rooster around and NOTHING happening with any of them? I'm not sure exactly what day it is, because at first we didn't realize what she was doing. Trying to remember back, this seems to be about day 19.
