Okay, as a person who may will be getting these birds sometime next year and are getting Isbars this spring is inbreeding a high issue with both breeds? If so would it be best to get different substrains to make each breeding flock more "diverse"?
I am slowly developing my flock of black Swedish hens and I hold suck plans on doing that with them in hopes of developing my own strain
Don't start a flock with stock from the same breeding group. It is okay to start a flock with stock from the same breeder as long as they are breeding multiple pens of cream legbars and you pair hens and cockerels with mates from different breeding pens. If someone has one cockerel and a pen full of hens then don't breed them together to start a flock. The same it true for any breed. Generally, working with in the same line will give you the best results but you want hens that are all closely related (full sisters is preferred) and a cockerel that is a few generation removed from the hens in the same line. You can use an unrelated cockerel if one from the same line isn't available. From crosses we made within the A,B,C line the problems that we saw were red ear lobes, a wide range of down color and markings, floppy combs on the cockerel, a wide range of crest shape and size, I wide range of mature weights, a wide range of body shapes, etc.
