Roy 0 Report post Posted March 16, 2019 It is generally thought that breding Black face to black face results in too many dead in shel or chick die in a few days. BF X BF is supposed to be lethal gene. Normally I do not pairtwo birds of same mutation but to check this I three times paired BF to BF. My results were justs as good as my other breeding. If anyone else has any expereince of breeding BF X BF, I will like to know their results. Share this post Link to post Share on other sites
