My cuckoos didn't start laying until almost 3 weeks after my speckled sussex, and my sussex are a week younger. Since they've been laying, I get about 5-6 eggs a week from each of the 3 and one of them gives me a double yolk egg 1 or 2 times a week. For my needs, this is perfect as it's only 2 of us and it gives us enough to share without being overwhelmed with eggs. We got chickens primarily as bug control and they have been awesome! I like the personality of my marans-friendly without being terribly pesky. I can handle them all easily and they come when they're called. Not skittish at all but not pushy either (my speckled sussex can tend towards being pushy about treats and pets). The eggs are absolutely lovely as you can see in this pic. They are even darker now that they've been laying longer. They're larger than the sussex eggs too. In all, I think these birds are a great addition to my flock and I really enjoy them.
