This is super helpful! I got 4 layers, 2 Plymouth Rocks and 2 Easter Eggers 3-weeks ago. The 2 Easter eggers are the mean ones to the Rocks, but lay consistently. The Rocks have not laid an egg yet in 3 weeks. Iassumed that separating them to make sure they are all getting enough food would be prudent. I was going to put the Easter eggers in the tractor and leave the rocks in the caged/coop 8'x7' to encourage them to lay. I assume being in the tractor on the grass is cooler because it's different. How do I even the playing field and get my Rocks to start laying?
