So my hens sour crop came back. I thought I got it the first time around but seems to have come back. I had given her monistat and it went away. I have been giving her monistat all this week but no improvement really. I then switched to a one day cream of a different type of anti fungal (this was about 10 hours ago). If this doesnt work I think I may need to try a more natural method. I looked for something on the butter milk treatment but I couldnt find it. Does anyone have a tried and true method of getting rid of this annoying illness?
