I have a female cocktail and she doesn’t sing like a male cocktail but very gentle and demanding.
I normally take her outside from the cage when I am at home.
One day my daughter said ouch ouch, so I said to her what’s happening.
She said to me I’ve got electric shock!
So I checked the extension cord near her leg and found out the wire came out from the cable.
The suspect was the bird. When she get bored she bit and nibble the cable until wires come out.
So when I take her out from the cage I have to keep eyes on her.
