I have a blue laced red wyandotte chick with a single comb. I don't know if it is a different breed or a genetic defect. I ordered them from McMurray hatchery. Sorry can not do pics.
you have all sapphire gems aka blue sexlink. they are like black sexlinks which will sometimes be back and copper or just black. sapphire gems will sometimes have copper markings
I have had the same thing happen with chickens. I think they just kind of forget about me. I don't know how to tame older birds but I would just say handle them more and be around them a lot.
