So I just posted about my roos, another question, sorry to bother everyone, but I am new to chickens, my experience last year with 9 "pullet", turned out to be 9 roosters! My luck! Now I have less roos and a lot more pullets! Question: I have one RIR at about 18 weeks, the rest are at 16...the roos included, will the roo at 16 weeks, try to breed the 18 week old RIR? What are the signs he is doing so? Sounds stupid, but he jumped her yesterday, she got away and voiced her loud opinion to his intrusion!
