Hi.
At 29-days-old, my Cayuga and my Khaki Campbell ducklings are now leg banded :

▬  For the Khaki Campbell duckling, I am using a 18 mm closed resin ring.
I 
know the recommended size is actually 16 mm for Khaki Campbell ducks, but I always prefer using a bigger size for my ducks... 
just in case.
(At least, I 
never have any issue with 
muddy leg bands cutting off circulation...! 
Or whatever...!!)
Size 
is perfect for a 29-days-old Khaki Campbell, so I don't think this little girl will lose her ring in the next few days.
▬  For the Cayuga duckling, I am using a 20 mm closed resin ring.
Again, instead of using a 18 mm ring, I prefer to use a bigger size than recommended...
Nevertheless, a 20 mm leg band look
 a bit too big for a 29-days-old Cayuga duckling...
For the time being, she has not lost her ring... so 
maybe it will stay on her leg...
...but if she 
does lose it, I will put it on her again in three-days. 
It should be good then...

Weird... I never had any black duck that was born 
brown...
...I would have think he would be Chocolate, indeed!
I... actually have a hen that look like that : she is 
tall, would look like a boy if not for her colouring, and has a so 
fine stance I am keeping her just for breeding...
...And she 
has made pretty babies...!
 (I'm happy to have kept her!)
From her very first days of life, she was really bigger than 
all of her sisters (only girls were born then)...
...And since she was my favorite, given she looked tall and strong... I was afraid she would end up being a drake (her legs were 
so apart she looked like a drakelet).
Thanksfully, she 
was a girl.
Voice sexing is not even 100% accurate : I had once a drake that
 quacked like a hen until he was almost 3-months-old...
...and
 this year, my first duckling I thought was a boy (sounded and looked like one) is now a 
confirmed girl - at around 2-months-old.
Sometimes, drakes are not 
sex monsters...?
They 
are their first maring season, but even then, you don't know... 
you could be lucky with him...?
(I know
 I was lucky with 
one of my first two drakes... and he is an Indian Runner. Even during his first mating season, he was
 not a serial rapist, and actually let the girls 
breath.)
They are hatching.
Have been since yesterday... but I still did not see any of the ducklings, so I don't know how many are already born, and
 what are their breeds.
(Waiting to see them is killing me.)
Size of a duckling is not related to its gender.
My first duckling of MAY 2024 was the bigger and stronger of all... and he actually is a 
she.
And the
 smallest duckling of my first ones born in MAY 2024 is now a growing, 
strenghtening boy.
(I really can not tell what duckling would end up being a male or a female by their size alone... or even by their stance.)
