Yea I was lucky I spent all breeding season finding, monitoring and collecting eggs from each hen so I was able to keep track of what hen layed what.
Petting zoo is a great idea..
I kept track of what hen layed what eggs and I had 5 eggs that did not hatch because they were in the wrong position, all those eggs came from the same hen, I belive that the shell was so thick that at the 2 week mark of incubation they did not loose the moisture like they should have and that...
