I have 5 chicks, all females, all 5weeks old. One is a Barred Rock, one is an australorp, one is an Orpington, and 2 are Wyandottes (silver and gold laced). All except the Wyandottes are freidnly to people. When I hold them, they flap and make HORRIBLE noises until I put them down unlike the other 3 who fall asleep in my hands. Are Wyandotte's just a stand-offy breed? From your experience, what breed of mine should be the most submissive, and which is generally the more aggressive?
