I have 4 pullets that are 9.5 months old. Two SLWs, and two blue Ameraucanas. One of the SLWs started laying at 8 months, and one of the blue girls started a couple weeks later. Both of the others have bright red combs, squat, and their pelvic bones are more than two fingers apart. WHY aren't they laying? I understand that different breeds and individual birds mature at different rates, but this is getting ridiculous!! I feel like I'm going crazy! I check the nesting boxes like 10x a day, and I don't understand why they wouldn't be laying. We've had a very warm week here, too, with temps in the high 60s, so they should be warm enough and be getting enough sunlight since its also been sunny all week. What's the problem? I've been waiting since August for these girls to lay, and I don't think I can take it much longer...I'm really starting to get worried about them. I've heard stories of hens not laying till they're over a year, but I swear, if that happens, I'll bawl my eyes out and be sooooo depressed. I thought about adding supplemental light in the coop, but it's kinda against everything I believe in because I feel chickens (and all animals, for that matter) should be allowed to do what they naturally do when they're ready to do it, but I'm so desperate I'm seriously considering doing it. What do you think? Do you think it'll help? I don't know what to do! Also, just as some background, they were molting in August when they were supposed to start, then we moved in September before they were done molting, and then, by the time they WERE done molting, the days were getting shorter and it was getting colder, so I understand why they didn't start then, I'm just wondering why the two have started now and the others haven't. How much of a difference can there be between when one pullet lays and when a pullet of the same breed will lay?
