Just introducing myself , ive not even got my aviary built yet as ive just moved into a new house (Nottingham)but im going to be having a mixed finch aviary , ive kept Finches in the past as a kid when my dad built me a small aviary alongside his Budgie aviary , but ive gone around 20 years without them now , im very experienced in keeping tropical fish and have bred virtually everything i could get my hands on , i was manager of a branch of maidenhead aquatics ,the biggest aquatic company in the uk , but i fell out of love with my fish , i think it was caused by my move up to Marine fish , i couldnt have all the breeding etc that i could before , it just seemed so expensive for very little reward, im one of theses that reads up on everything first beforehand ,im hoping to start my aviary build very soon in the hope of getting my birds towards the end of summer , im planning on an 8x6 shed with a 10x6 flight , i may then add an extra shed later for breeding cages but need to persuade the other half first .A question , to get started with though would be if any one could recommend a good oil radiator thats reasonably priced suitable for keeping my shed (size stated above) warm , reason being id like to try again with Gouldians , outdoors can obviously get too cold for them wheras the Zebras are fine , also if someone has any good tips on insulating the shed too , as ive been thinking about how to do this but its the roof thats got me stumped a bit , im no diy type so needs to be pretty basic .Otherwise i hope to learn a lot from reading these boards , will speak with you all soon im sure .Damian
