Thanks guys
I introduced my pair together in August and September
In regards to the incubation temps, I know couperi will definitely suffer defects if eggs are kept above high 70's - but is this same risk with the South American Drys (cribos)? Have you had kinks with temps higher than 70's?
In the late 80's, when I first hatched corais I had very little info to go on and incubated the eggs same way I did all my colubrids at that time - between 80 and 82F (which was actually considered quite low by most breeders in those days).
Of the 5 fertile eggs I had 3 hatch and they were perfect. The other 2 were dead in egg and appeared a little thin but fully developed and without defects.
These days I breed mostly Asian and European rat snakes and use temps in high 70's as this seems to produce best hatch rate and bigger, healthier hatchlings.
I would be very happy to see some hatchling yellow tails -they are my favorite Drymarchon

Cheers,
PatD
