The optimal temperature range for crocodile embryonic development is 87-91º F (31-33º C). Many crocodile embryos die if the temperature falls below 78º F (26º C) or rises above 95º F (35º C).
Oddly, the crocodiles' gender is determined by incubation temperatures. Lower temperatures (30º C and below) tend to produce pods that are entirely female. If the average temperature is around 31º C, the hatchlings will be a mixture of male and female. At warmer temperatures of 33-34º C, the gender is predominantly male. At even higher temperatures, surviving embryos are more likely to be female.

When a blue jay is born is it incubated?
There's a terminology problem here. Birds, including blue jays, lay eggs. The eggs are then incubated until the young birds hatch from them. If you consider "hatching" to be the same as "being born", then no, the incubation has already taken place. If you consider "born" to correspond more to the egg laying part, then yes, the eggs are incubated after being laid.
