My pigeons (rock doves), kept squashing ringneck eggs n chicks.. you could order pair of pigeons you want, or pre bred hen maybe even, n foster eggs under yours then every time and get breeding them faster. My parlors had and kept laying eggs upon opening up box from shipping, n eggs all fertile. parlors are extremely fertile birds, but can have rearing trouble if not kept in 20"" high cages, n given peaceful enclosed darker back corners to rear, as strains can be twitchy n spook easy, causing them to roll at random stuff, as they are trying to fly when doing so. low adult caging at three months on stops prob, as is then when they mature and lose total control of roll, but start off able and best flown until then (it streangthens muscles and helps them learm semi awareness of roll. i bred both parlor types, but down to one now breeding pair (their eggs left n almost hatched so couldn't send them, but they are stable line). usually i toss their eggs n id try to send them, but honestly don't know how well would work unless you pay extra to post office in care of (then you might as well have bought pair at that point as garunteed safe).
