Long story short I just had two hens pass away, from possibly different ailments, so I have been watching and feeling my remaining birds like a hawk. I have now 27 chickens and 12 ducks. The first two birds had different symptoms, and one seemed to have sever sour crop, and although I expressed most of it, I found her dead in the crate the next morning, and the other suffered from lethargy and stopped eating and drinking, and despite my efforts of giving water and egg, and antibiotics, she too passed. Fast forward two days, and I’ve been super careful to watch my birds, and I’ve been feeling everyone’s crops, and just this morning I noticed my absolute favorite hen has a half ball sized hard knob of food in her crop. But I can reshape it and massage it around, but it’s quite difficult. She hasn’t had anything to drink yet since I locked her inside to post on hwre before I let her get anything. She’s acting totally normal, and was quite upset I locked her inside. What do I do? I can give her coconut oil and water or I can go buy something, I have acv but don’t want to throw everything at her if it’s not needed. Advice appreciated
