Males have testicles.
Buy it a drink. If it throws it in your face, it's female.
This is very hard to do, but this is how I can tell my guineas apart. The female makes a two sylliable sound that sounds like "Pot rack" or "buck wheat". The males tend have a little longer waddles on the side of their face and make only a one syllable sound like " chi" Females are the nosiest ones. Hope this helps. I have many guineas and this is the way that I can tell the difference
males tend to have bigger shoulders than females. females have different hip shape than males.
males have smaller heads then females
females give birth.
You look at the eyelashes.
Males have a shorter legs than females do. Males are smaller than females. Males bark if they feel safe in their habitat while females make a quiet croaking sound.
Males have a red gobbler and can fan out, females are smaller and have a blue neck males have penis's and males have viginas
Females (peahens) are brown and dull compared to the male. Males (peacocks) are quite gaudy, with a flashy eye-spotted tail used in displaying to females and rival males.
Because the males a penis and the females don't.
Females have smaller genitals and the males have a dot on them .
Yes all full grown females are bigger then the males, males only have bigger tails.Also you can tell the difference between the males and females by looking at your guppies and the ones that have the most colors are the males and the females are plain. Well not all females are plain they have some color but not a lot!
