Hello everyone,
After moving all of the food bowels and toys around to get Crikey (also known as the bird shark, the kraken) to guard the food less I decided to look for another friend for them. She was guarding slightly less but I was moving things around nearly every day and Billy was still depressed despite having more access to food.
I had a look online and found a little fella for rehoming, his buddy had passed away and he was moved to the kitchen as the infant was trying to pull down his cage all the time. The lady rehoming genuinely loved him but knew living alone wasn't fair. After a quarantine period I moved him downstairs, it was a slow introduction as I think Crikey had never seen a budgie that wasn't green but Billy was so excited. He started living in the large budgie cage as of yesterday and it's going ok. He stood up to Crikey (he did previously live with a hen) and she's chased him a but not excessively. Billy is so happy having another friend, he's eating a lot more and is much braver, he's stood up to Crikey quite a few times in the last 24 hours when previously he never would.
So everyone meet Cosmo (formally known as Del Boy, I do still call him Del Boy sometimes!), he's around 8/9 months old (from what I can work out from the timeline given), he's the blue and white one. He reminds me a lot of my old boy Archie, very mild mannered, likes to sing along to the radio if it's a good song. He's had a few test flights, hopefully now having access to large space to fly he will become amore confident flyer. I've added in extra food bowls just in case. Due to him living in the kitchen I have been keeping a close eye on his breathing, I couldn't tell if he just had squeaky vocalisations or if he was wheezing so I have discussed with the vet and I am nebulising him to be on the safe side. He only makes the squeaky sounds when he's really upset after a big event (his first flight for example, which I think was the first time he had every properly flown and it also happened when he flew around a lot and ended up on the top of the curtain rail as I think he wasn't sure where to land).

Nice to hear everything is going so well!
