i hope the pics show up but i rescued a normal male pigeon of the street who is not releasable. i bought a frillback pigeon a few months later who turned out to be female. they have had a few young since then and one of the babies ended up with an extra talon and toe protrusion on his hin toe.... what happened my two female breeders and my male are completly unrelated. i seperate all my young by gender to avoid inbreeding and i keep them away from my male. so far all my young are female, my male young have all died.
