When do light brahmas start laying?

Now my eggers on the other hand will only use one box I've tried moving eggs but nope they all will only lay in one box and if i move it they will lay them on the ground where it should be lol

I'm having a brahma problem... she is seven months old now and her comb hasn't reddend and she has never squatted... how do I get her to lay???

I know this is late and the hen should definitely be laying by now, but diet, lighting and genes are what control laying. If your chicken is healthy and of age and not laying, typically one of these is not right.
