Weight loss at laying age

[Kaesi2020]

Hi everyone, my 21 week red sex link pullet has been laying an egg daily for about 2 weeks. The eggs look and feel good. I have noticed no changes in behavior but I have noticed weight loss in this pullet. She eats and has an appetite but she looks thinner since beginning laying. Her wings are more pronounced and her body looks and feels thinner. She has always been a little smaller than my other five pullets but I'm curious of weight loss after laying is typical? I plan on weighing her but just wanted to see if anyone had experience with this. Thanks! In the pics she is the red sex link up front.

I've never experienced that. They usually continue to gain weight as they mature.
Looking/feeling thinner can be from molting or worms.
