Gender of my Serama and Silkies help

[Ktovarez]

First time chicken mom here - I know these little guys are VERY young - only 3 weeks but I was reading there were a few early signs of gender in Silkies. Anyone have any guesses??

1. Serama - yellow with black on back - orange feet
2. Silkie - all brown
3. Silkie - all yellow
4. Silkie - various shades of brown, looks like a chipmunk!

Sorry they are not the best pictures, I had pretty bad lighting! Any help is greatly appreciated!

Way too early, try again in a month or so.

Too early. I think 5-8 weeks would be the easiest you could tell with silkies, but not 100% accurately.

Serama will need another week, right now I'm leaning pullet. Silkies are notoriously difficult. 14weeks is average for better sexing.
