Yeah sour, I wondered about that too. But she has no feather wear on her at all like the flock 'favorites' do and I haven't noticed any 'gang' activity towards the hens since the weather turned cold. She is the only hen with these symptoms.
I just went out with DH. She was sitting with another hen looking quite puny, poor baby. I checked her crop and it was fullish and solid. No mushiness or sour smell. She wasn't happy about it but she got 1/4th cc of Safeguard down. I'll see how she is in the morning.
I'm working on my young cockerel pen. I usually separate them the first of Feb which is usually when the hormones start to creep in to play again. January though can see 10 degree below 0 weather here so I like to keep as many little bodies in the coop as I can for warmth. And frankly it's cold enough that everybody just wants to keep their feet warm on the roost as much as possible and put the he-ing and she-ing on hold.
