If a female is determined to have babies, she will constantly lay eggs and that may be bad for her health. I bought a large bucket and filled it with play sand. Then I looked for some large branches, which I put in the bucket. These are natural sitting perches for the birds and they have more wood to chew on. I put new branches in the inside once a year.
Parakeets get along with many types of birds.
In this picture you see Zebra Finches. They are all having a ball and it is fun to watch them in summer or winter. The Zebra Finches are very funny and constantly build nests. They will steal anything for their nests. Parakeet feathers, grass, dog fur, spray millet etc.
