I have a white Bantam Cochin Roo and was thinking about letting my Large Lt Brahma run in his pen. Will he breed her and if he does will I get Bantam or large fowl chicks? Or is this a totally bad idea? Also, can I let my large fowl run with my bantams....which I used to do because they were all hatched together, but I separated them because I had a LF roo, but he is leaving so I will only have the Bantam roo. My Bantam girls seem to be more aggresive than my LF so I am not worried bout the Bantams. Thanks!
