Firstly thanks every one who has posted. I have leaned from each one and have had my question answered in full and also thought more confidently about paternal incubation.
Yes i will use a rack in an emergency and want to try paternal if the female has sufficient fat reserves.
This was a wonderful surprise learning point for me. ‘Minimum safe incubation temperatures’ as opposed to the tiny temperature range advised, the only place I had previously seen lower recommendations than the internet was here @t_h_wyman prefered (not minimum) incubation temps of 86f/30C.
Thanks for the info both. I will probably go for 30 but now not scared if it goes a bit below.
It was not what I was asking so I didn’t expect it here, but I have been looking for this information online for ages unsuccessfully.
That gives incubation set ups so many other possibilities beyond the normal ones if you don’t mind waiting a little longer. It also reassures me about small temperature fluctuations.
(I have edited and added minimum temps to the title to hopefully help others find that information)
