Can chicks hatch in long summer?

Yes, you can. Egg hatching not only needs external conditions such as temperature, but also has a great relationship with the pores on the eggshell. There is an air chamber at the blunt end of the egg. When an egg hatches, the chick that hasn't hatched needs to breathe air, and the chick breathes the air in the air chamber. There are more than 7000 invisible holes in the eggshell, most of which are distributed near the air chamber. Outside air enters the eggshell through small holes and is stored in the air chamber for the unhatched chicks to breathe.
