Help sexing my 6-week old chicks

[Mae_day]

Hello! Chicken newbie here. These are my lovely Black Copper Marans. Does it look like I have 2 females (right) and one male (left)? Also, anyone know what could be causing the feather loss?

I can take more pictures if that will help. Thanks in advance!

edit: a few people have pointed out the swollen crop. After researching, I think it may be sour crop or impacted crop. It looks like most of the time this can be treated at home. I’ll try a few things and if it doesn’t get better, I’ll get him seen. Thanks to those for pointing that out! It does look worse in the angle of the photo than it does in real life!

Looks like you could be right on the genders... the one on the left looks like his crop is super swollen, but it is hard to tell from the angle of the picture.

I believe you’re right about the sexes. Not sure about the feathers. Is that a lump or is his throat/crop puffed up?
