I bought 7 sex link hens at a chicken swap on 8/18. Gave 3 to a friend (I keep my chickens at her place). Supposedly, at the time I purchased them, they were all laying, or so I was told. I figured it would take a couple of weeks for them to adjust to a new place and they would begin laying (again?). The middle of September one of the hens (the biggest and leader of the flock) began laying, my boys saw her. Shortly after my leghorn pullet started laying (but I knew she wasn't laying yet when I got her and is the only white egg layer). But that's it. None of my other hens are laying. The end of September 2 of the 3 hens i gave my friend started laying, and were laying double yolkers at least a couple of times a week. My friend has 4 hens and a roo in a small triangle tractor where they stay all day. I have 6 hens and a roo who free range for, on average, a minimum of 5 hours a day, usually at least 4 days a week. The rest of the time they are in their tractor, which is a 4x8x22" high run with a 4x4x3.5 coop on top. They get unlimited supply of layer feed, scratch, oyster shell and tons of food scraps. They are all friendly and, once caught, will totally chill out in my 4 and 6yo boys laps. I also got a not quite laying EE who is still not laying. Now the sex-links are molting so i know they aren't laying now, but is there some way to tell the age on them so I can figure out if they are younger/older than i was told?
