Just curious... If I had say.. 10 hens and a Roo... How many generations could I hatch from this group without inbreeding? I've heard of people having the Son of their original roo take over.. so obviously he's doing the naughty with some birds that are at least half related to him. How many generations could this go on without defects popping up? Can anyone think of a simple easy to follow system that would allow for a closed system similar to this without inbreeding occuring.. say if I seperated into 2 or 3 flocks and exchanged Roos/added new Roos every couple of generations? Or would it be possible to raise 2 or 3 generations from an original flock of 10 hens and 1 Roo, and then bring in a new Roo whenever the old one gets.. old. Ideally, it would be nice to not have to bring in too much 'fresh blood' (sounds yucky that way) and buying a Roo is alot easier for diversity than buying a group of hens... I just like the idea of being able to raise my own flock without having to rely on others too much for genetic diversity. Obviously being 'chicken happy' I would end up adding/importing chickens whenever I saw a cool/pretty/spunky new breed I didnt have, but for the sake of argument, what could I get away with?
