Does anyone know a fast way to fix a crop disorder that isn't too dangerous to the survival of your chickens? Today I found out that one of my hens definitely has a crop disorder; I checked her crop in the morning and it was full. This makes sense, because I had recently thought that she was having difficulty eating. I don't think the disorder has developed into sour/impacted crop yet, but in any case, I need it to clear up quickly because I will not be at home for almost five days; starting mid-day tomorrow. The person who will feed my hens while I am gone knows nothing about handling or treating chickens, and teaching this person how to handle and treat my chickens is totally impractical at this point. I have given the sick hen some paraffin oil; she produced droppings that were mostly a clear liquid immediately after, further confirming that she is unwell. Would it be safe to make her drink some water with acidified copper sulfate in it now? Would using the homeopathic remedy 'Antimonium tartaricum' do anything?
