Don't buy what they're peddlin! One of my Orps was the loudest lady ever.. preaching so loud before she laid.. my husband thought we had a goat dying.
All birds are individuals regardless of breed.. you may have to move out the noisy ones.. on to their new homes.
Please understand that inbreeding is not the same for chickens or poultry as it is for mammals.. Line breeding or clan breeding are both fine choices. Doing the cross correctly matters.. meaning son to mother or daughter to father.. but preferably not brother to sister. There is LOTS of information available regarding this subject. It takes several generations of CLOSE inbreeding in poultry before deformities start to pop up.. the first notable concern would then most likely show up in the form of decreased fertility or decreased vigor before deformities.
I also thought Orpington would be the perfect bird back when I started.. it sure was on paper. But in reality not so much.. they were slow to mature (*for table or laying), bossy in the flock, I experienced what I think was GENETIC fatty liver hemorrhagic syndrome in one lady despite NOT feeding excess treats and using only high quality formulated ration.
For me.. I like straight combs.. but choose Wyandottes.. they grow fast and dress well for the table, raise their own chicks, cold hardy, forage well, etc.. available in so many colors as well.. you could even go with black, blue, and splash laced.. red wyandottes.. and keep a variety so you can tell them apart a bit but still have them breed true (essentially).. Or if keeping silver and gold laced could have them be sex linked.. via the silver gene.
Colored leg bands are commonly used to tell birds apart when keeping.
One quick note on the autosexing Bielefelder.. they grew very fast and dressing out well at 4 pounds at 16 weeks. However the ladies were extremely late to lay compared to other breeds.
The Deleware I tried.. didn't meet the paper perfection described.. in weight or laying.. but sample size may have been too small.
I haven't read the whole conversation yet, being barely on page one. I'm sure there has been lots of great feedback already.
Hope you are enjoying BYC!
