I have a small flock that untill recently, consisted of a male serbian highflyer Dale with his (unrelated) mate Lilly, there three children. two are male and one is female. i also have 3 homers one female two males. there were four un-paired pigeons in all, three male and one female. two of those were Dale's youngest children (maybe 5 months old). recently Dale's mate was killed by a hawk, leaving him very lonley. he and his son Corleone have paired. the kiss, feed each other and mount each other. i know that it is his son not his daughter because dale and lilly always produced "sex-linked" ofspring, the males being brown and the females white. they spend mpst of their time kissing and cooing in their nestbox taking turns hoping in and out of the nest boal. should i interfere?
