Can I keep multiple budgerigars in a large cage without aggression?

Thanks for reaching out about Alfred. Not sure if there is one distinct answer for your situation. Trying to keep the whole group together should be attempted first as budgiergars are social animals. Provide multiple feeding and water stations, perching areas and hiding spots. This can hopefully decrease aggression. Good luck.

It depends how large your cage is. The standard minimum cage size recommended by bird professionals is 12- by 18- by 18-inches for a single bird. This cage size is fine if your budgie is outside of the cage most of the time, but if you have a cage-confined budgie, it's going to be much too small to keep your bird happy and healthy.

It might work, however once both pairs start breeding and raising young, that cage is going to get crowded fast. It is best to keep only one breeding pair per cage to avoid overcrowding, as well as any fighting over shared spaces such as food, water, nesting material, etc.

There should not be a problem if the birds are slightly different ages, as long as they are getting together well and not fighting (something that can happen with same-age birds as well.) Making sure everyone has equal access to food, water, perching space, etc can help prevent fighting, as well as providing a cage that is large enough for both birds to move around, exercise, eat and sleep. The cage you currently have is awfully small, and they only appear to have one perch to sit on, which isn't best. Moving them to a large cage and adding in some more enriching toys and perches is best.

Budgies are social animals. Just because they fight sometimes doesn't mean they hate each other. They often interact to enforce a social hierarchy. If you need to keep them separate, try letting them out at the same time to have periods of time together, although this could stimulating the re-establishment of their social standings. Good luck.

I am sorry for the loss of one of your birds. Another budgie would be an option. A gradual introduction would be needed along with close monitoring to prevent aggression and injury. A larger species would not be recommended.

Thanks for reaching out about Tweety. Many bird owners have only one budgie, and the vast majority do well as long as there is mental stimulation. These parrots don't like to be along, so either bird or human company. The problem with adding another bird, is not all birds get along and in a cage there is no escaping aggression. If you have a return policy and get the birds as a trial run, that could work. Also, new birds should be quarantined to limit transmission of infectious agents. Good luck.
