we have just started with 4 australorp bantams we think they are between 7 to 14 weeks old, only sure of 1 is a boy and 1 is a girl but no idea on the other 2 yet, the boy started crowing this week and the girl seems to be dropping what looks and smells like the white of egg but no shell or yolk?? today we have bought 3 girl columbian wyandottes and they seem scared, but our australorps are very friendly.
