Can anyone tell me if these are roosters or hens?

Did you buy them all as day-old chicks? I wonder if they are all the same age, since they do not seem to be developing quite evenly.

Yes, they were all the same size when I bought them - all as day old chicks.

All are pullets, and yes birds of the same age mature at different rates.

Thank you for sharing! I was so worried I had 3 roosters.

Do chickens of the same breed I bought at the same store on the same day age differently?

100% yes.

I believe you have all pullets
