New chicks, male or female?

[MSO]

My chicks have hatched! I’m hoping someone could help me!! All less than 18 hours old. The the hens that layed these are a brown layer from a hatchery, not sure on the breed they are just called browns but they are sexable as yellow cockerels and red hens at hatching. The rooster parent is a Rhode Island Red and very dark in colour.
these are my chicks: share what you think!!

Sounds like the hens are red sex links, but that only works for the first generation. These guys won't be sexable at hatch. For gender you're going to have to wait until their 6-8 weeks.

You'll need to wait. Around 6 weeks, you'll begin seeing differences in comb and wattle growth. By 12 weeks, saddle feathers should become apparent.

Thank you for the replies! I was hoping the colouring would help since there are just 2 distinct looks among them, but I’m happy to play the guessing game for a few months!
