I have a group of 13 Black Copper Maran chick and this is my second go at this after a Raccoon attack killed all the pullets, so I need to get this right. Anyway I noticed as I was shutting them in last night one of them was wheezing a bit, when I came this morning to let them out I could hear him from outside of their little coop. This same little guy has been sneezing so I pulled him from the flock and seperated him and started everyone on antibiotics (Duramycin-10). I then noticed another one later in the day starting to wheeze a bit so I pulled that one too, and now there are 2 in the sanitarium. Does anyone have any advice? I just kinda have to get this one right, I want to have these Marans bad.
