Is this baby chick a rooster?

[OFWGKTA]

Ok i GENUINLEY dont know if i posted about this or not, so sorry if i did i dont got good memory

This babies tail is throwing me SO off, "he" is the 3rd youngest but looks like hes developing faster than the oldest, both born by the same two parents, both silkie mixes, but the younger babies tail is getting long and curled like a rooster, and the oldest is small and fat like a hens, my camera quality SUCKS but trust me the tail is longer and curlier in real life

Old baby: 4 weeks, 5 days old
Young baby: i forgot maybe like a week younger

Tail shape/size means nothing with sexing chicks. Plus the males don’t get in their male specific feathering until at the earliest, 12 weeks. The comb and wattle development at around 6-7 weeks can usually tell male vs female. So I’d highly suggest to retake photos when they are at that age.

Judging by it's comb development it's a boy
