My hen is almost a year old now and I just discovered today that she is nesting on a few eggs. Not sure how many at this point. This will be my first batch of chicks. Anything I should know? Also how will I know if the eggs are fertilized? I don't have an incubator so she'll be the one keeping them warm. Any tips will be appreciated! She is a frizzle cochin and the daddy is a silkie. I'm soooo excited!!!
