Replacing A Mate

[DaveR 0]

Hi all. I just signed up to the site to ask for peoples opinions. Until yesterday I had two budgies named B1 & B2 a male and a female. I bought them both together as young birds about 4 years ago and they have always been together in the same cage. They were good companions for one another but unfortunately yesterday the female had some problems with an egg that become stuck and even though the vet removed it (there were actually two eggs removed) B2 didn't make it through the ordeal ☹️ 

I'm concerned now for the one bird that's left in case it becomes lonely. I'm wondering if I was to go out and buy another friend for it would it be better to choose a bird around the same age or will it be okay to introduce another younger male? 

The alternative is to find someone with other budgies that would be willing to take B1 to join their flock but Im unsure how well birds adapt to new members. 

Any advice is greatly appreciated. 

Dave.
