Thanks for the info..I have 2 sick Bantams..no one else..so I am trying everything..including having them in the house during our cold weather. They seem to be perking up after giving them .05cc of Ivemectin. I had already started them both on antibiotics given to me from another chicken lover. This is not like people medicine! lots of guess work. They eat fine, just gasping occasionally, and sneezing and shaking their heads. Last night I noticed a small amount of blood coming out of the hens nose. The Roo's comb was almost colorless and even black, but he did just get his tail wooped from another rooster I have. Now his color is coming back. This is my first time around so I am trying to figure out a game plan, and a check list of things to help me identify when there are problems. Everyone else is healthy. I have 5 seperate pens with 6 in three if them and 3 BAntams in the other 2. They don't socialize well so I have always kept them seperate.
