i made a avairy from an old rabbit hutch that never got finished to be onist. its only about 3fT Height 1 1/2ft Width 3 1/2ft Length. not the biggest i no but the old cage i had was about 2ft Height 2ft Length 1ft Width its a bit bigger not much.
ok ill keep them in the old cage inside till april no problem i was trying to get a heated mat for the cage outside but unsuccessful at the moment no of any place cheap to get one? also i have made a small box inside the outside cage for them to sleep in put a bit of hay in there and they seemed fine bit shakey by 10pm which is the latest i've left them out side till. i was putting them inside the cage out side say 10am then bring them in late in the evening. they seemed fine. but i'll hold on till april then and get a heated mat by then.
i've had 1(yellow bird) for 5 years and the other(black bird) for 3 years. i only had one because my dad caught it flying round the marina then i bought it a buddy as it graved attention from me allllll the time. is it possible the one i've had for 3 years is a male even tho when i bought it from pets world they said it was a female but the one i bought from them is the one on top of the other one i've had for 5 years. and the one from pets world/black bird makes all these crazy noises to the other one im assuming thats some kinda mateing thing?
any help would be great and thankyou so much for the previous posts

i was going to leave them outside all night soon glad i did'nt now
thank you david
