I have 4 chickens between 2-3 years old. The Ameracauna and the Sexlink lay almost every day. But the Welsummer and the Leghorn barely laid any eggs all summer (we're talking maybe 1 egg every 2 to 3 weeks). Last summer, all chickens laid a ton of eggs, no problem. They all eat organic soy and corn free pellets. They have plenty of fresh water, a clean and safe coop and they get to roam around a huge fenced in yard all day eating bugs and whatever fruits and veggies they can get their little claws on. I've read a bunch of threads on here and my best guess is that they stopped laying due to stress. We had an incident months ago where we lost a chicken to a raccoon. This was back in the spring and I think that's when they stopped laying. All the other threads I read about chickens that stopped laying due to stress said they started laying again after a few days but it's been months of this. They don't "seem" stressed. They act like the other 2 chickens. They run up to us when we go outside to give them sunflower seeds and they seem generally ok. I'm just wondering if they've ever going to start laying again or if they're permanently scarred. Any help is appreciated!
