I have one chicken with what I believe is sour crop and pendulum crop. I have been trying to help her for quite some time now. I have tried medicated water, little to no food, "burping her", yogurt, etc. Nothing seems to be working. She has not laid in a long time (possibly months). I have another chicken who, starting today, is shaking like she is cold. I have put a heat lamp over her, but she is still shaking. She has not laid that I know of. I have both these chickens in the house, but I am worried about that as I have 2 baby chickens in the house also. (They are not near each other) and I have eggs in the incubator.
