I was asked by a new chicken owner about what she should do for her sick chicks. I inqired as to the symptoms and what she described to me sounds VERY much like CRD. She keep them in her basement with some other chicks who have not gotten ill yet but is worried about them. She also is concearned about the small flock of healthy birds she has outside. I've never dealt with this myself and was completely unsure of how to advise her other than I know it is something that can be fatal and if the bird survives it will be a carrier. I also can not be certain that CRD is even what her problem is but it sounded like what I have seen described as CRD before. She mentioned that she had had some sick birds back around Christmas and said something about then vaccinating them???? My thought there was, Why would you vaccinate sick birds? It's not like it is going to cure what they already have? At any rate, what are your experiences with this? I thought as a poultry owner it would be wise to broaden my knowledge.
