[SirBrookalasBrook]

Please could you find out what gender pekin bantams i have. I know they are meant to be really easy to sex but i'm selling them and I dont want to get it wrong.

Chick 1

Chick 2

chick 3

Chick 4

Chick 5

chick 6

Chick 7 ( that chick is way to curious )

Chick 8 (phew! only 3 more to go)

chick 9

Chick 11


At last done, that took me for ever. Some of them are really against having there photo taken, but some are really photogenic

3 and 11 seem like cockerels. All the rest look like pullets. I’m also not too sure so take my guess with a grain of salt

 

[SirBrookalasBrook]

thank you
i also forgot to say they are 4 and a half weeks old

 

[SirBrookalasBrook]

i thought 4 might be
because it has a huge comb

 

[SirBrookalasBrook]
