I noticed this last night, but I thought maybe her feathers just extra fluffed on that side, tonight when I pulled my chickie out to take a look at her I looked even bigger! Her chest looks and feels swollen on the right side. It looks like she got a breast implant or something. She is still happy chirpy and active, eating and drinking. She had some scrambled egg a few hours ago and has been drinking normally, I change her water twice a day and wash the whole container every afternoon. It's just her chest/breast area. should I take her to vet in the morning? She's only four weeks old.
