I am treating my pullet for a sour crop, this is the 3rd time now. I just can't seem to shift it, as soon as she is better and i let her out to freerange, within a couple of days it returns. I have been treating her with yogurt and garlic and acv, then slowly introduce soft food in small amount, gradually building the amount up every day. This 3rd time, i withheld food for 24 hours then she got yougurt with fresh garlic mixed in, 3rd day (today) she got yogurt with a small amount of oats mixed in with the yogurt. I am now thinking that after 3 attempts at clearing her, maybe i need to concider medication to clear it once and for all. Does anyone know what medication i should give? Also any suggestions on natural remedies appreciated. All suggestions and ideas welcome.
