I just went out to look on my 1 month old Silkie. I was rubbing her chest and noticed it felt squshie, so I looked closer andd she has a quarter sized area on her chest that almost looks like a water balloon. Has anyone else had this before, this is my first time with chickens and my first experience with something being unusual. She didn't try to get away while I was touching it so pretty sure it doesn't hurt. Any information would be wonderful.
