It is just so easy for birds to get bad diseases. I had a cockatiel many years ago now, that I kept in a huge cage in our yard in Southern CA. 10 months of the year is is perfect for birds outside. I thought it was cute that the small wild sparrows would go between the bars and share the food with my bird, who seemed to like the company. Then one day, my bird was dead in the cage one morning. No warning, but I believe the cockatiel caught something from the wild birds sharing his food. Pet birds are not immune the the things the wild birds carry. Neither are chickens. Outside chickens can get things from wild birds, like the before mentioned bird flu. Sadly, my chickens will have to be in their run unless I am out there, and the run and coop will not give wild birds access. It is just the world we live in, Newcastle disease is in CA, and I am just barely in AZ, one state away. The quarantine zone is a 3 hour drive from me. So, I am a little paranoid.![]()
Oh no I'm sorry to hear that

It's sad loosing birds regardless of what type they are. They all have such unique personalities.
It's awful about the diseases going around over there, I'd be paranoid too. Not so long ago we had a outbreak of bird flu in the UK and birds had to be kept indoors and all sorts. Luckily, we didn't have our birds then.
Luckily our aviary is double meshed and nothing can get in like wild birds. However, with any aviary or just keeping birds in general has a risk of them getting disease no matter how vigilant you are with cleaning.
We aren't keeping our aviary much longer as we are rearranging birds and wanting to use the aviary space for something completely different. A family member of mine is more involved in the breeding of parrots and things more than myself. He just recently got a breeding pair of Jenday Conures and they are by far the noisiest bird we've ever had...even noisier than our Grey we had

I just focus on my own little project of Silkies rather than the parrots.
I hope your birds all stay healthy and happy and get through the outbreak!
