Its starting to sound like your roll outs arent rejects. If you dont maternal incubate at all. How long after the lay are you splitting them up? Maybe she didnt have a chance to regroup? Ive had snakes lay in 30 minutes on the other hand Ive had snakes take 6 hours and regather a stray (fertile egg during the process)
They are taken from the female once they are found. Usually the night after work or in the morning before work so it could be hours before i find them.
