Yesterday I found that one of my cochin chicks had a pasty butt. So I got a warm wet paper towel and got it cleaned up. I have been checking on it frequently. This afternoon, it had just a little dried poo, so I soaked her bottom in lukewarm water and cleaned her up and put baby oil on her vent area. Is there anything else I should do for her? She is eating and drinking. What are the chances that she will make it? She is 8 days old, if that matters. Thank you!
