Within the past 6 months, she has gradually lost weight. It has been very gradual. It seems now, almost overnight, she seems skin and bones. Her comb is pale and she has runny poop. When I picked her up this morning, she smelled "funny". There was no other way to describe it. It was sort of sweet smelling, and I am pretty sure it was from her rear, but I am not certain. She also has a hard lump under her beak on her neck - not really where I think her crop would be I don't think... She seems to be eating, or at least picking through the food. It's hard to tell. We have only had three hens in our lives and still have all three of them. They are "illegal," and we are really new to this. We immediately thought it could be worms, so we treated all three with Safeguard on Saturday. Her comb did seem to get a little color on it the next day. I also have Corid arriving today just in case. I would hate to lose her because of our ineptness. What course of action should we take? I would really appreciate any suggestions!
