I am in the midst of a Cocci battle with my BO's, but that's a whole 'nother story on another thread, but still relates.... This morning I found one of my White Rocks showing some signs of Cocci...OH. NO. Not them, too! They do not reside together yet as the coop addition is still under construction. But they can see and hear each other. I have been giving the BO's the treatment dose and everyone else the prevention dose. The White Rock in question also did not look as "pretty as the other girls...almost as if her head and neck were being pecked! White Rocks will be 4 weeks old tomorrow. Whenever I have had to force feed, I held them on their backs, holding down wings, etc. But just a little while ago, she was being overly frisky and I had to kinda wrap my hand around her and hold her firmly (but gently!) against me. I felt an awful lump near her throat. About the size of a "shooter" marble, I think that's what it's called. The lump was pretty hard. Naturally, I came here. I did some searches first and actually just found out what a crop is! I found a lot of info, but mostly for older chicks and chickens. How much danger is my baby in? Will olive oil really help? Massaging? Massage downward or upward...do I want whatever is there to come out or go down? BTW, her poop is not bloody...don't think it's Cocci. Please help.
