I do not cut because I am impatient if it was the case I would cut on day 30 or so, if I can wait through 52 days I can assure you I can wait a few more I cut on day 52 to prevent possible drowning.
To me breeding animals means putting all the chances on my side and doing everything I can to ensure successful hatch. (it goes from incubating using an incubator to cutting)
I do not recommend cutting if you do not know what you are doing because like with everything else there are risks.
