brother/sister...keep roos?

[MadabtChickens]

I have 1 coop which right now holds 4 RIR hens, 4 Delaware pullets, and 2 Delaware cockerels. I know I will be getting rid of one of the cockerels. My daughter is in 4-H and we just started in entrepreneurship. She plans on selling eggs and chicks from our eggs. We got the 2 cockerels and 2 of the pullets from the same person. That person got them from a friend who hatched the chicks, so it is possible that they could be sister/brother. Is it okay to breed chickens that close in relation, or should I get rid of both cockerels? I'm really new to all of this chicken stuff, so your help is greatly appreciated.

As far as I know yes. I plan on doing that with my barred rocks the are brothers and sister.

You can do it yes. The results will depend upon the quality of the birds that you have. You may get something really nice or really poor. It will magnify whatever your bird's good and bad points are.

After this mating you will need to get some out side blood for sure to mate with the ones you raise from the brother/sister.

Thank you. I do have 2 pullets that are not related to the roos right now. Do you mean I need to get a different roo? I won't be keeping any of the chicks until we need to start replacing layers in about 2-3 years.
