Young budgerigars can get along with old budgerigars, but it may depend on the individual personalities of the birds. In general, budgerigars are social animals and can form bonds with birds of different ages. However, there may be some initial adjustment period as they get to know each other and establish their hierarchy within the flock. It's important to monitor their interactions and provide plenty of space and resources to ensure they can coexist peacefully. **

You should change the food for budgerigars if it becomes moldy, stale, or contaminated. Additionally, if the food has been sitting in the cage for an extended period of time and has not been eaten, it should be replaced to ensure freshness and quality. It's also important to regularly monitor the food to ensure it is not spoiled or attracting pests. Finally, if you are transitioning your budgerigar to a new diet, it's important to gradually introduce the new food to avoid digestive upset. **

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. **
