I own 5 Japanese bantam chicks and 1 adult, im wondering, how early can you tell Japanese bantam gender? Because im 90% confident one chick in particular is a male. Thanks! (Posting pictures in one moment.)

Comb of one in question

compared to another.

The one in the back (not the one in front, or the sebright on the left) is the one in question, the tail is bigger and higher, the comb is redder and bigger then the others, theres some wattle coming in, and that one LOVES to perch, they all do, but that one likes it more along with the sebright. A few like it more then the others.
All 4 weeks old.


Thanks! Really apoligize for the delay. Grumpy mama gave me some trouble.

Thanks guys! Thats what i was kinda leaning towards but wasn’t sure. The others look very similar to the 2nd photo one, does that mean their most likely pullets?
