Texas A&M Sexing???

[TERMINATORATIS]

I tried vent sexing at 3-4-5 weeks without success, 6 weeks it was pretty obvious but I made 3 mistakes (of 20+) at 7 weeks it was no prob

Good luck!

YOU TRIED TO DO SEXING NON MATURE BIRDS. THEY REACH MATURITY AT AGE 5-8 WEEKS IF FEED PROPERLY!!! WEEKS 3-5 THEY ARE STILL INMATURE. THATS THE REASON YOU CAN'T MAKE DETERMINATION OF GENDER. ONCE THEY START CROWING YOU DON'T HAVE TO CHECK THEIR VENTS! IT'S SO SIMPLE, BECAUSE THEY REACHED SEXUAL MATURITY.
