birdcage

Hello! I am getting a 13 week old cockatiel, he was raised in an outdoor aviary. I’m just wondering if the transition to an indoor cage is okay and if there are any special precautions I need to do? The cage I have right now is this one, I’m aware it’s 9cm under the size requirements. It’s 46 x...

I'm about to make this type birdcage but: I Don't know how much the materials would cost for the cage(also need the details of how much a diy large 210 cm x 400 cm x 210 cm cage would cost)
