At 6 1/2 weeks. This is my Niece Cheyanna and our chicks. On her L shoulder are Norbert and Lemon Cuckoo-Big Bird, R shoulder is Lemon Chalet. From Left to Right on her arms are Pitta, Midnight, Briony, Thursday and Arnold. They are about 6 1/2 weeks old. Arnold is twice the size of Briony and Norbert and he is getting a large and floppy comb. The girls are all developing crests and Briony has some funny wing feather on her right wing, They seem to stick up. As you can see they are very social and friendly.
