I lost her ): I don't know why the infection got her so much worse than the other chicks, but it really messed with her. She hadn't grown in size at all since the day she hatched and by the end every breath was a mouth wide open gasp. I wonder if she just had something wrong with her to begin with, and the cold aggravated it. I did get a lot of runts in the group.
At least the other chicks are growing large and strong, not a sneeze left in the group. I'd like to replace her since she was my only dark brahma, but I've never seen dark brahmas sold anywhere around me. Dangit.
