French Black Copper Maran

Is this some kind of growth on the lower front of her chest? She has had it for months now. Doesn't seem to bother her.

Hello and welcome to BYC! Glad you joined.
That looks like a pendulous crop. You might want to consider researching a crop bra.

Hiya, and welcome to BYC!

It appears your hen has what's called a pendulous crop.

This first informative article talks about that and other crop issues: https://www.backyardchickens.com/ar...w-to-know-which-one-youre-dealing-with.73607/

This is another very informative article to help learn about crops and more ways to help them. https://www.backyardchickens.com/ar...ntion-and-treatments-of-crop-disorders.67194/

I hope one or both of these will help you help her.
