I agree with all the above, except the worming. But to each his own, but I am warning you, you are at a tricky stage. What I would expect, is the pullets that are laying, will slow in laying, but should lay all winter. However, the ones that are not laying, there is a strong chance that they may not lay until February.
I frequently hatch in the summer - generally May, June or July, even August. That is when my hens go broody. Anything hatched in June, won't make 5 months til November, and if they will lay in the winter is iffy, as in I don't count on it. I have one pullet that hatch mid June. She is really growing, but has not reddened up at all. And I have 3 chicks maybe a month old.
However, they will come on to lay, early in the spring, and generally are very good layers.
