Fertile Eggs | Birds
Temperature For Incubation
As a general rule, most parrot eggs are best incubated between 37.2°C and 37.5°C and at a humidity of approximately 56%.
After breeding, if the eggs are fertilized, the hen will lay her first egg in about 25 hours. Another egg will follow every other day. The average “clutch” is 4-8 eggs, with a second clutch following , in about 4 weeks.
It's important to know that some hens never lay eggs. On the other hand, some hens, with out a mate, can lay eggs. If you have a single female laying, do not remove the egg(s), unless broken. This will only encourage more laying. Allow her to sit the eggs. Usually, after a week or two, she'll realize the eggs are not developing and abandon them. At this point, you can safely remove the eggs. Don't forget the second clutch in about 4 weeks. To avoid this, cut day light time to 10-12 hours, (the mating hormone in is triggered by light) this will help curb the urge to lay. Limiting the light can be done by moving the cage to a darker room, pulling drapes early, turning lights on and off later/earlier. It depends on your finds location and circumstances.
Egg laying can deplete her of Calcium. This needs to be supplemented with Calcium Rich Foods. Some foods rich in Calcium are broccoli, cauliflower, spinach, apple, mango, cucumber, tomatoes, rice, hard beans (cooked), pasta, eggs (and shells), dark orange veggies; carrots, sweet potatoes, butternut squash, and many grains.
Vitamin and Mineral supplements can also be purchased in the form of liquid, or powder.
It's not uncommon for the parents to destroy the eggs, and sometimes eat them. In many cases, where the hen eats the egg(s), it's due to a Calcium deficiency.
Then comes the growth cycle. The babies are fledged ( weaned by natural parents) in six to eight weeks. Hand fed are weaned in eight to twelve weeks. Individuals vary.
