Her grey would be too young to be a breeder, but that is a good question. I had a Nanday Conure too. He was old when I got him, but wow..was he ever a squaker!
I know all about squakers. When we lived in WPB, we moved into a house near the water, and our neighbors had a big privacy fence, but we knew they had birds...they woke us up every morning.
When we finally met the neighbors, they introduced us to their birds. Actually, they were
her birds. She had 200, and kept most of them outside. So, you can imagine what our mornings sounded like.
When they split up, she had to move into an apartment, and needed help with her birds. Bill and I volunteered our back yard, since she was going to be in an apartment nearby, and it would be convenient for her to take care of them.
At some point, she gave us a young Nanday, then we acquired the Quaker, but I don't remember how. Pam eventually found another place to keep most of her birds, especially the larger of the bunch, and I ended up with only about a dozen of the smaller parrots and a pair of grass parakeets in the back yard.
The caged birds always attracted the parrots that had been released, because someone decided they didn't want the burden, or had escaped because their wings hadn't been clipped. That's about the time I noticed the Cherry Head pokin' around and sitting on the cages. He showed up at least once a day. So, I set a trap, and that's how we acquired the Cherry Head.
When our daughter came along, we no longer had the time, or the finances. I know, we've all heard the story, and berate those who do this, but it was best for the birds. They MUST have that social interaction. So, we re-homed them.
Anyway, that's my bird story.
It's great reading for the 7 year old. She puts the bird on his playgym and sits and reads him books every night. He nibbles on his lava rock while she reads, then feeds him his fresh green parsley and cheerio snack. They are bonding well together.
At this rate, the bird will be reading at a 1st grade level in no time.
