by pair or group..??

Question
hi tara, good day...
im christian but friends call me ian...
i love birds really, and i care a more than a dozen of parrakets for a couple of years now and i put them on cage by pair... and recently a friends of mine give me some of his african lovebirds and a cockatiel...
for years that i care for parraket, putting them in cages by pair doesnt really works, reason, i dont know...
and so with this im thinking to put them together in one big cage about 3 meters wide by 3 meters length and by 2.8 meters hight, the parraket, african lovebirds, and cockatiel... is this a wise idea or not..? what are the circumstance of putting them together..? well this three species get along with each other..? with regards to nesting, i've been using nest box yet still i seems it doesnt work out so good considering that we have a tropical climate down here in the philippines.. and so im thinking of providing them a coconut husk instead of nest box, is it a good idea..? consediring that though coconut husk is a bit i guess that a nest box yet its space inside is a bit small compare to a nest box..?
if you have more idea and suggestion aside from the question i have above, i would be glad to hear them from you... thanks...
tel next mail, hope to hear from you tara, take care always, GOD BLESS YOU...


Answer
Hello christian and thank you for your questions,

If the cages are large enough(2 feet x 2 feet per pair) and they are prodived with plenty of food & water & a large enough nesting box then the budgies should breed. No it is not a good idea to house the love birds, cockatiel & budgies together, love birds have bad tempers with other birds and will attck the small budgies and the larger cockatiel, the budgies would be ok together thou some adult hens do not get along. I hope this helps if you have any more questions just ask.
