Yes.. pink skin.. and pink beak.. together with bright yellow down usually means the chicks will turn out to be white.
However, I have many coloured pigeons.. black and red.. and they also have pink beaks.
My favourite pigeon is a 'mutt', where the female white fantail cheated on her mate with an old Dutch Capuchin.
The resulting pigeon has one black eye, one yellow eye and a white head with a black body. He also has a huge tail with a big white bar down the centre. I was going to sell him as I do not want mixed breeds in my loft... but he is just so cute and friendly.. and unique looking too.
Breeding and keeping pigeons is such fun!!!
