I'm new to the world of chickens and I need help. I started with 29 one day old baby chicks that are 10 weeks old today. One of these chicks was a White Crowned Black Polish that I was crazy about since day one. Soon after his crown feathers started to come in the other chicks had a go at them and almost pecked him to death by the time I got home. I immediately isolated him and treated his head with antibiotic ointment (that was all I could think to do). Six or seven weeks went by and his crown feathers had still not come back. After so much time in isolation with little improvement I decided that in or out made no difference and put him with the rest of the flock. He didn't last 30 seconds (literally) before another rooster had him by the back of his neck. After breaking up the squabble the other rooster chased him out of the yard. Most of the birds have their little stand-off/stare-offs without actually fighting or attacking but this time was different. Plus the Black Polish never bothered to defend himself at all and seemed overly timid around all the other chickens. As soon as he came back in the yard a HEN ran straight for him and took a plug of feathers out of his back and he just ran off again and wouldn't come back in the yard. I don't want a fighting rooster on my hands but what can I do to make him at least defend himself against a blasted hen? After this incident I knew he wouldn't make it without being pecked at continuously so I brought him in my basement (don't worry it's unfinished) made a six foot diameter, two foot tall pen out of of cardboard (that for whatever reason he doesn't bother to get out of) and filled it with pine shavings. Tonight I noticed that he is constantly rubbing his beak on everything, scratching his face with his feet, shaking his head, and what seems to be sneezing. Then I discovered that he has what looks like a runny nose. Of all the birds in my flock he is probably the only one that I can say this about but I will not cull this bird. If that means I have to keep him quarantined in my basement for all his days so be it but I'm not going to let him go without doing everything in my power to help him get better. If anyone can help me do that I would be incredibly grateful.
