I have struggled with this too simply because I want to maintain/increase (ha, yeah right) fertility and egg laying.
I think I have a long road to hoe simply because tracking egg laying is not easy unless each hen has their own suite...
But... I am determined to do my best to try to maintain the quality in the line I have which is approaching it's 100th year.
Any advice for different easy methods to track egg laying?
Trap nesting is the most effective, or you could let each hen spend some time in separate pen.
Many of the old time chicken men believed that the faster feathering hens and roosters produced the best layers, as well as the best feather quality.
I tend to agree with this form my experience.
