Hi, I read on this site that it is ok to breed Mother/son Father/daughter. It is called line breeding, apparently. What about brother sister. I have 3 chicks and 1 Roo that hatched 3 wks ago and I am trying to decide if I need to invest in some more B.C. Marans eggs or not to get good stock. I do know that if you breed within the line it concentrates their characteristics good and bad. (Since they don't have teeth, I won't have to worry about the cosmetic effects of inbreeding, ha ha) What do you guys think?
