I'm selling my last few hens to a friend this afternoon ( but I'm getting more babies next spring, Lord-willing) and I have one hen who recently started molting. I felt her abdomen and it feels hard, not soft like most of the hens'. It almost like there's a lump under her vent. Or like a tensed muscle. I've felt it there a couple of times, so I don't think it's an egg. One other hen seems to have the same thing. I'm guessing it's nothing - is that what a non-laying hen feels like? But I'd feel bad if there was something wrong when I'm giving them to my friend.
