I currently have 4 standard hens; an EE (5 years old), a Production Red(1 year old), an RIR (4 months old), and a BO (4 months old). I also have three bantams; a BTW Jap. Bantam (1 year old, a Bantam Cochin (1 year old), and an OEG bantam rooster (1 year old). I REALLY want fertile eggs to hatch in the bator and for my broodies, but the only hen I get fertile eggs from is my Japanese Bantam (I don't know why my Cochin's eggs aren't fertile). I would like to get fertile eggs from my standard hens, but I am worried a standard roo would kill or injure my bantam roo. I am considering splitting their shelter in half and putting another cage on the opposite side. That way I could separate the standards and bantams and avoid roosters fighting and large hens bullying bantam hens. I am wondering if this is really nescecary, or if the two roos can coexist in the same cage. Thanks!
