ok this is my 2nd year breeding as a hobby. last year i had a clutch in the incubator @ 82 degrees and they hatched on day 61 with no problems. this year i have another clutch in the incubator @81 degrees. nice fat plump white eggs. great right ? well heres is where the ? comes in. they are on day 85 with no signs of being ready. now i know with lower temps they will take a lil bit longer but is there a "danger" zone for time? i mean should i slit them or just let them go?
