Is there anybody who would be prepared to give a fantastic home to 3 Lineolated Parakeets?

I took on 4 over a year ago and lost one to a respiratory infection. All were in poor health and I took them because I felt sorry for them. I have brought them round to good health, and whilst they will never be 'top form' birds they are very sweet.

I enjoy buying and taking care of my parakeets.What would you suggest to get them better acquainted with each other.Is it common for them to fight?What are the best conditions for breeding?best season

I have a really important question to ask...I hane a set of parakeets, one is 10 yrs old and tha male is 6 yrs. old////
Last night While I was sleeping I heard them ruffling around (yes, they and my other birds sleep with me) so I got up, turned on the light and seen that my male was haveing trouble balancing....At firdt I thought maybe he pulled his tail out grooming himself but it is all there...I can't explain he just looses balance....I am extremly worried about him and plan to take him to the vet tomorrow,,,If anyone has ever dealt with this please respond.

Tell us about your birds? Linnies seem to be relatively rare in aviculture - I've seen photos but never actually met one. What are they like as companions?
