I have a red sex link hen that just started laying again. She went broody this spring but was sitting unfertile eggs. I replaced them and she hatched and raised 8 . I was about to give up on her until she just started laying again. I assume her eggs are fertile since I have 2 roos in my pen, one nice buff and one Americauna. I want her to hatch another clutch so I was going to start leaving her eggs in hopes that she will get broody and want to sit. My questions are how long do I give her and how long will the eggs hold up until she does start sitting. It dropped to about 27 degrees last night and I didn't know if the cold weather would hurt them any. I assume about 7-8 days and she will start sitting if she is going to?
