8 week silkie, waddle development

I personally would never put any weight on behaviour to determine pullet vs cockerel until they are older.

I agree. I thought for sure my cochin was a cockerel based on her attitude. She was feisty and would play the chest bump game with my male. But, she is a she. I learned behavior isn't always indicative of either sex at a young age.
