I have a 9 week old rooster I have raised indoors in a heated room. His mother and a brother nearly pecked him to death when he was born, and I rescued him. The StepMama still hates him. I now find out he must be reintroduced to the flock or he will try to mate with me, as he thinks I am his Hen! His siblings have been raised outdoors so they are fatter and more feathered and able to cope with the cold. The temperature is to get down to 20 degrees F here the next few nights. I'm afraid the cold might shock my Roo who has been indoors in the heat. How do you think I should best proceed? Would it be possible to let him play with his siblings outside during the day and then bring him back inside for the cold winter evenings?
