I have a flock of 25 hens almost a year old, consisting of easter eggers, red sex links, black sex links, and white leghorns. I also have nine 10-week-old pullets which are barred rocks and silver-laced wyandottes. Along with my 10 week pullets I received four mystery chicks which as they grow up I am pretty sure are Rhode Island Red cockerels. I wasn't planning on having roosters but now that I have these cockerels I am thinking why not keep a rooster or two around and see if I end up with some chicks. My question is, will those roosters plus those hens result in good egg laying progeny? What kind of mutt chickens will I end up with? Thanks in advance.
