My budgie keeps making a spitting sound
(Coventry, West Midlands, UK)
I recently got a new male budgie who was 10 weeks old and put him in with my other male budgie that is about a year old. At first they didnt really get along and had a lot of fights but they have now calmed down. The other day i heard my younger budgie making a spitting sound at the older one and chasing him round the cage. Is this terratorial or is there something i can do to stop this?
