My husband has the framing up for the outdoor aviary for my cockatiels it is on the 2nd level deck (so away from rodents etc) Its 5' wide 11 ft long and 7 1/2' tall flooring will be first a layer of wood (I'm horrible with the names LOL) then tile. The roof will consist of alluminum angled and 2 wood doors will be added main door then about 2 ft of the aviary is going to be inclosed with 2nd door and wire to ensure no escapes we can change the food from this area and cleaning shouldn't be bad. Now he wants to add plants inside the aviary so Im wondering what plants and or trees are ok for cockatiels to use and is it recommended? We also want to do natural perches so what tree branches are ok to use? Along with toys, swings and will be adding stuff as we think of it can anyone think of additional items I may need to add or haven't thought off? The cockatiels I rescued about 2 weeks ago have been switched to small cages because they had been in a cage about 2ft tall and 3 ft wide and there are 21 of the tiels total I've seperated them into smaller cages so we're trying to get this up for them as quickly. I've had them quartined since I rescued them as I also have 5 tiels in my bedroom. Also anyone know of a good site to get the outdoor heater for the aviary? My husband plans on also covering the sides with tarps on windy days but the where the deck is we have half of this enclosed and can come out & sit with them also the side of the house doesn't get windy and is clear of trees etc (atleast where the deck) Am I forgetting anything? Oh any ideas as to feeders and water dishes that they won't make to much of a mess with??
