Will she continue to sit on bad eggs or should I be trusting her instincts on this?
Thanks in advance!
Yes a hen will continue to sit on bad eggs. If you feel confident that it has been over 28 days, I would candle the eggs. Be careful when handling the eggs as rotten eggs can explode without warning.
Give her a couple of weeks and she may mate again providing you have a tom that know what he is doing. I say this because I seen toms try to mate while facing to the rear. LOL
This season I had hens hatch their eggs and a few weeks later mated and started laying eggs while still caring for their babies.
One suggestion, make sure to candle the eggs so you can discard the bad ones early on.
Here is one of my hens that mated and stated laying again. These poults hatched May 10.
