I have a hen that's 10 months old and has never layed an egg. Today I caught her sitting in the nesting box on a fake egg, is this a sign that she's gonna start laying soon? I'm not completely sure of her breed, possibly a rir.
I've only caught her sitting once, seen her checking the box out one other time. She's not grumpy at all. She's been eating 16% layer crumbles. When she's walking around and you reach down she squats. I think she's gonna start laying soon. She has 3 other hens her age and a rooster and hen that's 6 months. There are two older bantam hens too, not sure of their age
Squatting is a good sign. You can also check her pelvic bones to see how close she is to laying, there's a how to and pic near the end of this article:
