How can i change the pairings of the four pigeons i have?

Answer 1

It is a common practice in the pigeon racing community. Put a breed pair together on the nest and the other breeding pair in the other nest. When both pairs have the eggs, put the eggs from the pedigree pair into the mutt pair nest. Break the mutt pair eggs intermediate. The mutt pair will raise the babies of the pedigree pair and that pair would have egg again. You will have 4 babies from the same breeders.
