The main reason is that the male is simply curious. he wants to know why the female spends all her time in there. She won't come out to be with him, and being social creatures, budgies love company. So if the female won't come out to the male, the male will simply get as near to the female as he can.
if it is a female it means it is breeding condition or is ready for mating
A female budgie is called a "hen".
You have a female budgie, male budgie's do not lay eggs.
The answer is to avoid doing this. If you put a male budgie and a female budgie together, they will mate.
All it means is that he/she is in breeding condition but he/she will have to be at least 12 months or older before ready, really its nothing to worry about.
whatever color you dye them
the bird is getting annoyed at the boy but it will pass. i had a similar case and now they are breeding :)
yes I would say it is possible.
she must be sick.
female or still young
The alpha female is the breeding female in a wolfpack.
Because they are probably a mated pair, and she is in charge.
