My experience with my birds is that they lay later each spring as they age. Weather can have an effect too. When mine laid their first spring, they started in mid April. This year mine did not start laying until mid May. I will be setting my first batch of eggs tomorrow.Great! I just asked because the adults I have now they were hatched y very late summer and started laying in very late spring, 20 days before summer day ( at exactly 8 months of age).
I was wondering that now they are adults they might start laying a little earlier like early to mid spring? Or they lay when it is already hot climate.
Also here last spring was slow to come regarding temperatures.
