Bird eggs can hatch baby birds in 15-21 days.
Bird eggs usually hatch in 15 days, which is natural hatching, while artificial hatching time is around 21 days. However, due to the difference in temperature between different places, it is not unusual for the eggs to hatch a day or two earlier or later. The incubation period of the bird's eggs will also be affected by the temperature season and the temperature of the breeding each year, and warmer seasons and suitable temperatures are more conducive to the reproduction of the birds.
If artificial incubation to ensure that the incubator temperature is balanced, fixed temperature at 37.8 ℃ or so, regular turning of the eggs, the fifth day of the first egg test, eliminating spermless eggs, 19 days to fall plate, fall plate to 20 days in the evening on the chicks to break the shell. However, depending on the size of the eggs, species and ambient temperature and the performance of the machine, the incubation temperature will vary, but the maximum will not exceed 39 ℃, the minimum can not be lower than 36.5 ℃.
Precautions
Don't turn over the eggs in the first three days of incubation, and stop turning over the eggs after 15 days, you can take a marker pen to the eggs to mark them, when turning over the eggs, you can clearly know which one turned over and which one didn't turn over, so as not to turn over the eggs unevenly resulting in stunting, generally one turn in the morning, one at night and at least 2 times a day to ensure.
On the 17th day or so, the young birds began to peck shells, pecking shells during the cover can be covered loosely, pecking shells during the do not go to peel, so that it comes out on its own, if it has not been out of the shells, you can be pecked shells peeled small thumb-sized hole can be.
When incubating in winter, we must pay attention to the temperature, cold winter, the whole incubation process only need to illuminate the eggs 2 times, illuminate the eggs too much easy to cause flash eggs, resulting in the eggs of dead sperm and dead fetus.
