Soon afterwards, the young Koi will begin to wriggle then, gradually, over the next few hours, it will break out of its 'shell'. It will take three to four days for the Koi eggs to develop and the fry to hatch at temperatures of 68 -7l.Koi fry can develop at temperatures as low as 63, in which case their incubation will take five or six days, or as high as 77, which will decrease their hatching time.he day before the Koi hatches the eyes in the egg will have a shine to them.

Insect and spider eggs may take a matter of days to hatch, but some insect eggs overwinter and mâ¦ay take over half a year to hatch. Birds' eggs may take around three to four weeks but even that is not consistent - the kiwi's egg has an incubation period of 70-80 days. The eggs of reptiles also vary. Crocodiles' eggs, for example, take around 65 days to hatch, whereas tortoise eggs may take anywhere between 70 and 120 days to hatch, depending on the species. There are three species of mammals which lay eggs (monotremes, comprising the platypus, short-beaked echidna and long-beaked echidna). Monotreme eggs, once laid, hatch in just ten days. 2 weeks
