Is a crooked comb a sign of inbreeding?

[gojira]

A lot of the hereditary faults are caused by breeding brother-sister matings. Remember also that the female also has a lot to do with the Comb shape. Try bringing in a new line and single mate with a female or two and mark the chicks so you can identify later.

No hereditary faults are caused by breeding brother sister matings. Breeding that closely might result in genetics faults being expressed more frequently than in other systems of breeding, such as outcrossing. The same genetic faults can appear in outcrossing systems, but typically not as frequently. Inbreeding and linebreeding can be used to determine which faults are in a line of birds, and to remove them.
