Black Swan Confusion

A couple of weeks ago, dad discovered that Agnes was building a nest inside the swan cottage and it wasn't long before he discovered an egg.   He also saw Bella and Agnes making googoo eyes at each other.  We thought Bella was a girl.  Could Bella be a boy?
Dad brought the egg inside our house and placed it in a basket.  The next day, another egg appeared and dad collected that one too.  Egg number 3 was laid too and dad actually saw Agnes lay this one so he's sure it's Agnes laying them and not Hazel.
Dad put the eggs into the incubator and replaced two of the eggs in Agnes's nest with wooden eggs so she wouldn't feel so bad.  

 A few days later, dad discovered that Agnes had laid another egg so now she's sitting on one "real" egg and 2 dud wooden eggs.  Agnes, Buster and Hazel all take turns sitting on the nest but we're pretty sure that all of the eggs belong to Agnes. 

 If you look closely, you can see the egg underneath Agnes.   How come black swans don't lay black eggs?  It would make more sense to us.

 Buster and Hazel waiting their turn to sit on the eggs.  Maybe they'll be parents in the spring?

 This is Bella.  She never goes inside the swan cottage and we've had VERY cold weather with biting winds lately.  There is a heat light inside the house but she prefers to brave the elements.  Maybe she/he thinks four is a crowd inside the cottage?

 She's preening and loves it outside.  Dad finds her/him in the morning with frost on her feathers.  She does have a straw nest on the shore where she naps in the daytime but she sleeps in the water at night. 

 This is the bubbler inside the black swan's fenced in area.  It keeps the water defrosted.  It causes quite a turbulence.  There is another bubbler on the other side of the fence for the other waterfowl.

 That's slick ice in front of Margaret and Penny, the Mute swans. 

 Hi Midgee!!!   All of Speckles ducklings are doing great!  They're hardy birds and very happy!

 Angel Whooper is doing her morning stretches after finishing her breakfast. 

 Dad says that Bella is less than 2 years old and she's not old enough to be a father if she is, in fact a boy so are the eggs in the incubator going to hatch?  Is the egg underneath Agnes going to hatch?
By Valentine's Day, we should know if I'm an uncle and Molly is an auntie. 
Are you as confused as we are?!

So until next time...........

Love ya lots♥
