My lemon brahma has had a large crop for quite a while now but yesterday she was very quiet and today shes moving her neck like shes got something stuck and keeps standing alone all puffed up. I dont really want to hold her upside down to make her sick incase she dies, so ive been reading about using epsom salt in water to clear the crop. How much epsom salt do i put into how much water? Ive also been putting apple cider vinegar into the water shall i continue with that aswell or change back to just plain water while treating her with the epsom salts. Thank you.
