They don't seem to squat for my rooster, and they never have squatted for me when I pick them up. They are healthy and happy, and have never had any issues. They get either layer feed (18% protein I think?) or a 'mixed flock' feed (I think it has around 20% protein, but I'm not sure).
They both free range everyday, so it's possible that they lay somewhere random. I have seen both of them sitting in nest boxes and they both (very occasionally) join in with the other girls' egg songs. Thoughts?
