In addition to one gold and one silver, I also have 2 RIR and an ISA brown. Both of the wyandottes are the least friendly of the flock--they don't want to be picked up and they don't come running to me like the RIRs. Also, the silver one who had a beautiful looping pattern seems to be the least favorite among the other chickens--she gets pecked and is losing feathers! I probably need advice about what I'm doing wrong to prevent this, but you may have better luck.
