The issue: My budgies are on either end of the weight spectrum.
Ollie is a little tubby around the middle. I don't think you could feel his breastbone if you tried. We like to joke that when he sits on our finger, he almost breaks it.
Sally is a poor little thing. Her breastbone is juuuust visible, and when you hold her, it's the first thing you feel.
The situation: Ollie and Sally live together in a cage. A metre away is wher ethey spend most of their time, on a perch of a size more suited to a cockatoo. I have recently installed a 'spiral staircase' (aka ropes like this
winding around the post of the perch, as Sally is 'disabled'. She is unable to fly for any distance, and really struggles to get height. She can fly easily from the perch to the cage, but if at any time she ends up on the floor (gets spooked by us walking past, crashes on her way to the cage or attempts to follow Ollie when he goes for a fly), she has to rely on us to get her back up. This was a problem whenever we were out, as she would have no way of getting back to her cage.
That issue is now resolved, but the poor girl is panting by the time she gets halfway up the staircase. She's so frail, and stresses so easily. Ollie meanwhile hangs upside down on the perch, squawking at her to hurry up.
Whilst I'm hoping that Sally will start eating more, she only eats seed. Ollie, on the other hand, is quite happy to eat anything that we are eating (though oftentimes he just makes a mess of it). Just the other day, he gorged himself on zucchini, the first time he tried it. It helps that he is a friendly budgie. Sally is anything but. If it was possible, she would have nothing whatsoever to do with us.
What I'm asking, is how can I try and get weight on Sally whilst maintaining (or hopefully losing) Ollie's weight? I'm planning to start trying feeding them the same as what I'll soon be feeding my breeding pairs, in the hope that Sally will follow Ollie's lead. But, Ollie really
doesn't need any extra food!
It probably sounds horrible, but I was (jokingly) considering clipping Ollie's wings so he had to use the 'staircase' too, and keep putting him at the bottom of it to make him run laps xD
