So, I've been following this on ZuPreem's website:
ZuPreem - Slow and Steady
I don't know how well it's working, they don't seem to be eating the pellets still. If it doesn't work I'll try something else.
But with this conversation process, it says to put seeds in their food dishes at certain times of day. I've been following it ok, but it got me thinking. What would happen if I put some seeds in my hand? I couldn't resist. They've been not tame for so long. I've been following reeb's thread (thank you for that btw!) about taming budgies, but nonetheless I tried it.
So here's what I did: I opened the cage door of the more tame budgie (the one that doesn't bite) and put my hand, with seeds in it, close to the opening. He, of course, had finished the daily allotment of seeds I gave him as part of the recommended routine, so he obviously wanted more. He perched on the bottom of the cage door and willingly ate out of my hand with one foot on it. I praised him and while doing so I tried to inch my hand away from the cage door. He kept backing away back into his cage, but came back to me. Anyway, after a few attempts, I got him out of his cage! This hasn't happened in years! After eating all the seeds out of my hand, he jumped off onto the top of the other budgie's cage. To get him back into his own cage I had to give him more, but this is quite the accomplishment!
The other budgie won't be so easy though. I tried the same thing on her and she just kept biting my finger. :/
So, in conclusion, I set out to get them onto pellets and got a different outcome than what I was expecting!
