Yes! Take The Boyfriend out immediately
. With birds, it’s “out of sight, out of mind”. So no, I don’t believe she’ll feel bad. Regardless, you have to do what’s best for Nimbus.
Also, be sure to not give her access to any toy or bed that can be perceived as or used as a nest. Rearrange the perches and toys in the cage (doesn’t have to be all of it).
If it were me, I would not rush into getting an additional budgie at this time. I would get Nimbus’ hormonal urges and egg laying under control. That’s the priority right now. Remember, any time you introduce a new bird (after quarantine) there is never a guarantee the two will get along, and you might need to keep them separately housed permanently.
