There are too many variables to know what an "average" cage is. Part of it depends on the dimensions of the cage, part of it depends on the shape of the cage, and a lot of it depends on the budgies themselves. Females in particular can be territorial and aggressive.
It can get a little crazy with so many budgies in one cage, but if the budgies get along and dont fight it should be okay for them all to nest in one cage.
If you want to breed budgies no because if they fall from the nest the chickens will kill them the same sometimes happens with adults so it is best not to even if you're not breeding
Most budgies will sleep at a certain part of a cage. If you have one of those small swing perches they might sleep there every night. It is nothing to worry about.
yes they can. I have had 3 budgies killed by rats in an outside avery. One had its head bitten off and one disappeared totally from a locked cage and i found the other one dead. They didnt kill the cockateils and it took me a while to work out what was killing them as the hole where they were getting in was not noticeable. Then i checked on them one night and saw 2 rats in the cage. I have removed the birds and put rat bait in.
The cage wires can be NO more than 1/2" (one-half inch) apart. Anything more and they can squeeze through. Guillotine doors can be opened by budgies and may need to be secured.
Yes I myself have more than one budgie they are both male but i suggest that you get male and female or two females because sometimes males would fight over the limited space also make sure to change the food and water daily and make sure they have plenty of space (some budgies like toys) and give them lots of love :)
loads. There are many things that are harmful to budgies, so be careful. In the wild they often live in eucalyptus trees, so if you but one of their branched in your budgie's cage, they'll nibble it.
for some reason my budgie and my lovebird get along and seem to mate. i don't think budgies and love birds get along.
in 1950 you could keep 6o in one cage
No one can say for sure how many budgies there are in the world. They originate from Australia, where it is believer that the wild population exceeds 5 million. Being the most popular breed of pet bird in the world, their numbers probably well and truly surpass that number.
Budgies normally sleep on one leg with their head tucked under their wing, standing up!
The answer is 4 canaries and 3 cages. You can check it on paper.
