Do pullets stop gaining weight/growing when they lay their first egg?

[Nenad]

I got one australorp pullet who is really small, not runty but around 1.6kgs and she layed her first egg at 7 months old and I was wondering will she grow any more? Her parents are normal utility weight but she looks like her mom in size but weighs less. She has good weight one her keel and body. She is on good feed.

Don't worry. Chickens sexually mature before they reach their full size and weight. They will continue to fill out for another year, and I've even seen a few get larger beyond that.
