Hi all. I'm newer to ducks. I started with 2 about a year ago, I have 4 now. I'm wondering if this gal has a problem, or it's just her. I got her about 2 months ago, she was about 4-5 months then. She's a Golden 300, I guess she's about 6-7 months old now. Here's a few pics I took today. She's the light brown one. She's got quite the bulge at her breast...that's what I'm concerned about. She is acting fine, eating, and swimming. She seems happy. Is this just the way she's built, or should I be concerned? Thanks for any input!
