It is possible for old budgerigars to fight with new budgerigars when they are first introduced. Budgerigars can be territorial and may feel threatened by the presence of new birds in their space. It is important to introduce them slowly and carefully, allowing them to get used to each other's presence before allowing them to interact closely. Providing enough space, toys, and perches can also help reduce the likelihood of fighting. With proper introduction and monitoring, old and new budgerigars can eventually learn to coexist peacefully. **

Yes, budgerigars can breed. They are known for their ability to breed easily in captivity, and with the right conditions and care, they can produce multiple clutches of eggs each year. It's important to provide them with a suitable nesting box and a balanced diet to support their breeding efforts. Additionally, it's essential to ensure that the breeding pair is healthy and of breeding age before attempting to breed them. **

Budgerigars, like many other animals, can exhibit same-sex bonding and mating behaviors. This does not necessarily mean they are "gay" in the human sense, as animals do not have the same concept of sexual orientation as humans. It is more likely that they are forming strong social bonds with each other, which is a natural behavior for many bird species. As long as they are happy and healthy, their specific mating behaviors should not be a cause for concern. **

Your two new budgerigars may be being bullied by other budgerigars because they are seen as intruders in the established social hierarchy of the group. Budgerigars are known to form complex social structures within their flocks, and introducing new birds can disrupt the existing dynamics. It may take some time for the new budgerigars to be accepted and integrated into the group. Providing plenty of space, resources, and monitoring their interactions can help reduce bullying and allow the new birds to acclimate to their new environment. **

It is not recommended to release budgerigars into the wild. Budgerigars are domesticated birds and may not have the necessary survival skills to thrive in the wild. Additionally, releasing them can disrupt the local ecosystem and introduce diseases to wild bird populations. It is best to find a suitable home for your budgerigars if you are no longer able to care for them. **

There could be several reasons why your budgerigars are appearing lazy. It's possible that they are simply tired or not feeling well. Make sure they have a balanced diet, access to fresh water, and a clean living environment. Additionally, ensure they have enough mental and physical stimulation to keep them active and engaged. If their behavior persists, it may be best to consult with a veterinarian to rule out any underlying health issues. **

There could be several reasons why your budgerigars are not drinking. One possibility is that they are getting enough moisture from their food, such as fresh fruits and vegetables. Another reason could be that they are finding other sources of water, such as condensation on their food or toys. It's also possible that they are drinking when you are not around to observe them. If you are concerned about their hydration, you can try offering them fresh water in a different type of container or location to see if that encourages them to drink. **

Yes, budgerigars are sensitive to smoke and it can be harmful to their respiratory system. It is important to keep them in a well-ventilated area away from smoke to ensure their health and well-being. If you suspect that your budgerigars were exposed to smoke, it is advisable to monitor them closely for any signs of respiratory distress and consult a veterinarian if needed. **
