I only had one BSL pullet and she was a sweet, gentle girl until a stray dog finished her off at six months of age. My cockerels attack my husband, sons, and eventually even me for nothing more than walking by them or standing near them. I finally sent all the cockerels to freezer camp at eight months of age. The one cockerel left with my production red pullets is taking his job of taking care of his girls seriously now that he's not busy fighting with the competition. I think I wouldn't get BSL cockerels again but would love to have some BSL pullets if they are all like the one I lost. She was not laying but would have started any day so I can't comment on egg laying abilities but her disposition was wonderful and she was a gorgeous girl. On that note, all my neighbors comment on what beautiful birds my BSL cockerels are.
