do chickens know better than to inbreed?

[cptbahama]

I don't really know of a better way to put it. We bought 9 blue andalusian eggs online. 4 hatched. we gave one away so we have 3 7 week old chicks. Their "mama" is a blue laced red wyandotte. In addition to these we have 7 other layers of various breeds. One of the 7 week old blue andalusian chicks is most definitely a roo. We have decided to keep him. We've been raising hens for 3 years now and this will be our first roo. My questions are:

Will he know not to breed his two sisters and "mama"?

What if he does? Would the chicks be deformed or somewhat so due to inbreeding?

Any other comments or advice welcome. Many many thanks!

No, they've no civil or moral inner code against it, in fact, they do so commonly. Line breeding and in breeding of related birds is done all the time.

Breeds of chickens or other animals is a human concept. To chickens, there are only chickens. Nature manages to take care of all this.
