Duck has big chest. Is this normal?

Tevyes Dad said:

Her crop is puffed up. That in itself is not good or bad. If she recently pigged out and her breath smells like nothing or what she just ate (ducks don't normally have a smell to their breath), she's probably just fine. If it doesn't go away (check first thing in the morning before she has a chance to eat) or she has a sour smell to her breath, she might be having some issues in her crop and they could pass or be very serious so in that case, I personally would take her to a vet because I don't know any better (none of my birds have had crop issues - but they have filled them up more than what is in your picture). Someone else hopefully can add more.

My duckling of 2 weeks maybe 3 has this same iissue. I relieved a ruptured air sack recently. He's looked this way when i adopted him 1-2 weeks ago. Got a Lil bigger, but so did he. It doesn't go away and feels fatty or poofy but not the same as the air sack. Understandably bc that was on his neck. Should I treat this as the same and try to relieve it?
