Hey there -- I have a hen with the same exact problem!
She is an older RIR, I think she's 5 this year. Her abdomen is swollen, but not hot, looks uncomfortable, but she's acting normal, and she is not egg-bound in any way.
She's been this way a while . . . but because she is happy and laying, we're just watching her closely. If anyone figures out what this is, I'd be thrilled to know for sure!
