1 1/2 week old chicks. Straight run… need to know a good way to tell between a rooster and hen at this age

[The-Chicken-Tender]

Hey everyone I am new here! Grew up raising backyard chickens but never had any as an adult until now. We got these chicks from TSC on 3/6/25 as soon as they came out on the floor. I know it is hard identifying roosters and pullets at this age but was wondering if anyone could tell me a tried and true method to being able to tell at this age. I can post pics if necessary but figured it would be hard to tell in a pic if anyone has some better ways of checking please leave as much detail as possible or pictures so I know what I’m looking at . One thing I will post pics of is my coop build that’s not completed yet

Don't forget plenty of ventilation in your coop.
No, there's no way to tell at this age, unfortunately.

How much more ventilation do you recommend?

The only way you would be able to tell for sure at this age is if they are an auto sexing breed. I don’t think you mentioned the breed. Were they sold as straight run?

They are Americanas straight run from tractor supply

1 square foot per bird.
I'd recommend something like this.

Yeah, unfortunately for the most part, you won’t be able to tell for a few more weeks.
