There's a special kind of suspense that comes with waiting for a hen to lay her first egg, and /u/basilandprimrose is living it right now. White feathered friends, 18 weeks old, no crowing, no laying, and winter closing in on New Zealand. That's a lot of uncertainty wrapped in feathers. We've been there, watching a coop full of perfectly healthy birds and wondering if they're ever going to get around to doing what chickens do. The good news is that silence, no crowing, means you likely have hens, not roosters. The quiet is a win. The bad news is that winter is a notorious procrastinator when it comes to egg production.
Here's the honest take: 18 weeks is right on the edge of laying age for many breeds, and the white ones are often a bit slower to mature than their colorful cousins. Add in the fact that you're heading into shorter days and colder temperatures, and you've got a perfect recipe for a delayed debut. Hens need about 14 hours of daylight to trigger laying, and winter in New Zealand isn't exactly generous with that. Your birds might simply be waiting for the sun to cooperate. They're not late bloomers in the sense of being broken or unhealthy, they're just playing the waiting game alongside the season.
If a reader brought us this exact question, we'd tell them not to panic and definitely not to start buying special lights or supplements just yet. At 18 weeks, you're still in the normal window. Give them until 22 to 24 weeks before you start worrying. In the meantime, check that they have a good layer feed with adequate calcium, keep their water from freezing, and make sure they're not stressed by predators or coop drama. The biggest practical advice we can offer is to be patient and keep an eye on their combs and wattles, if those are bright red and plump, they're close. Pale and small means they're still kids.
So here's our concrete point: you don't have a problem, you have a waiting period. Your white feathered friends are not broken, they're just on winter time. And when that first egg finally shows up, probably in a nesting box you'd already given up on, it'll be worth every anxious morning you spent peeking into the coop. Until then, keep the treats coming and the jokes flowing. Because honestly, watching a hen pretend she's not about to lay an egg is the best comedy nature offers.
