I'll hop on this thread. I have two Wyandottes, two Cochins and one Barred Plymouth Rock. They will be 20 weeks old in two days and I've not yet seen much indication that they're even thinking about laying. Spoiled ungrateful little brats. They passed last nights health check with flying colors, they eat Scratch and Peck layer grains, they have free access to oyster shells, and I add protein treats like mealworms and BOSS to help with their juvenile molt. I even have fake eggs sitting in the nest boxes. If they don't start laying soon, I dunno what I will do, but stew is starting to sound mighty tempting!
