for sure , when possible, if you can just take the perch out and put it back in the other cage
that would be perfect, less handling of the sankes in breeding mode..
I haven't had time to breed GTPs yet, concentrating on ETBs but if they are/act the same.
as we both mentionned, it's best to do the in and out.
I've noticed that they will lock the first night and then show no interest in breeding. by day 3-4 i remove him, try feeding if it's his week and the back he goes.. that slways gives me another lock.
the female swings her tail with interest all over the cage versus just coiled up and have no interest in the male. many leave the males in for months at the time during the breeding season, i've tried leaving him for longer and seems like the magic is gone after that first lock
I have a few PB males that i alternate with the females.. but not with all of them, because i keep certain males for specific females to make following the bloodline easier.
with hold backs, it's best if you know who the parents are
your caging sounds like a good plan and saves $$ at the same time..
