[sandy sea]

I have now three broodys. Day 14, 13, and 7. Should I candle the eggs? I have ever candled eggs before and new to broodies. What do I do?

My cousin in the west valley just had a hen that had 21 eggs under her.

20 hatched.

Nature knows how to do it's thing.

One nest has 20 eggs , the other two have around 12 each. Just wondering if I should candle them? What do I look for?
