Another chicken died

One of the Gascone chickens has been a bit weedy for some time. It had scaly leg which we treated. Most of it got better, but its feet stayed all gross. We were just treating it some more when it started drolling I read up about that and decided it might be sour crop. But when I went back to look closer she was dead. Not really knowing what she died of we didn't fancy eating her. They are having a bit of a bad time of it as she is the second one to have died recently even though they are only 18 months old. They are less skinny now though. We have been feeding them a little cat food for extra protein.
