I got this chicken from a backyard breeder about 8 weeks ago. I just noticed in the last two days that her chest looked very 'puffy'. My husband held her yesterday and made me realize that it was more than puffy, her crop seemed to bulge. I picked her up this morning around 8 am and massaged her crop. It definitely has food in it, but it is not hard or solid. It feels to be the size of an apricot. It is slightly squishy, but also definitely protruding. I did not get to her before she ate breakfast, so I cannot say for certain if her crop completely emptied last night. My chicks sleep in a pine shavings coop and have a 10 ft covered run on dirt. I have not put grit in their run, and have only been feeding them chick feed with an occasional meal worm as a treat. This is my first time raising chicks- am I over-reacting or is this something serious? (sorry for the pic of my face, I was taking a selfie and was more concerned about the pic of the chick than my face).
