Recently, my father came to live with us and decided that he wanted to get some chickens. He started with just one rooster and two hens. About a week ago, I noticed that the rooster seemed to be having a hard time breathing and, after some research, decided that it was either bronchitis or CRD. I immediately brought it up with my father, who told me that the rooster had been sick for a while, and rushed to the nearest feed store to buy some antibiotics and electrolytes. Since then, the rooster has died, my father "flew the coop" and I've been left with two hens that are showing the same symptoms that the rooster had. I know NOTHING about raising chickens. Currently, one hen appears sicker than the other and I've separated them from each other. I'm working on cleaning out and better insulating the shoddy coop that my father built on his own. Any suggestions or advice would be greatly appreciated! I don't have a problem with keeping and raising them myself, I just want to make sure that I'm doing everything I can to keep them from dying!
