5.5-6 week chicks - gender guesses?

[hollandaisehoney]

Howdy hi!

Some of my chicks are pretty obvious with their gender…but these 3 have me stumped. I got them in a straight run from TS and have been searching “signs of hen/roo” for the last 6 weeks. Can you see any obvious signs?

#1 Buff Orpington

#2 Sapphire Sky

3 Buff Orpington

Thank you in advance for your help! I know it’ll be clear eventually, but I do love investigating.

My guess is #1 is a pullet, #2 not sure (sapphires always stump me, including my own), #3 cockerel.

1 is a pullet, 2 I'm guessing cockerel, 3 is definitely a cockerel
