I have a pair of Lady Gouldians. They are 5 yrs old. The female looks to be getting old . She sleeps all the time except when eating. She's plump. She has some balance problems. Her beak is shrinking. This has come on over the last few months. The male is happy singing, bright eyed, exercises, does the hopping up and down When she dies, do I get him another friend? Can it be male or female? Does it have to be a Gouldian? Can he have 2 finch girls of another type?-Like a threesome? I really need help with this, I don't want my male to be unhappy. I am not planning on breeding.
