Changing a Bird's Food

I have a seed junkie. I cannot get him to convert to pellets.

With my last bird, a sweet, sweet cockatiel, I had no trouble. She'd eat anything I offered her. She'd even eat things I didn't offer her, and would try to steal food from my plate. When I first learned an all seed diet was bad, I found a brand of pellets available locally, Zupreem. She was a little reluctant at first and would eat all her seeds and then wait for more. But, the first time I gave her all pellets, she ate them willingly. I was able to add a small amount of seeds back in, and she would eat the seeds, the pellets, and whatever greens the guinea pigs were having that day.

But Digby, my lovebird, will not eat anything but seeds. He will eat his seed mix and he will eat millet. He will ignore anything else I give him. I've tried different methods to try to get him to eat pellets. I first tried just mixing the seeds and the pellets together. He picks out the seeds and then wants more. I've taken away all his food at night, then in the morning, give him only pellets. He won't eat them, and by afternoon, I've given up for the day and put some seed in with the pellets.

And it's not just pellets. I've tried to get him to eat greens, I've tried to get him to eat sprouts, I've tried to get him to eat Nutri-berries. I even offered him some cooked macaroni the other day. He bit it, and I thought he was going to eat it, but no, he would not eat it.

Today, I thought I'd try taking a familiar food and changing it just a little. I took a millet spray and boiled it. He started to take it from me, but as soon as he realised it was different, he refused it. I also boiled some quinoa and some lentils. I tricked him into getting a piece of quinoa, but he spat it out as soon as he realised it wasn't millet. He wouldn't even touch the lentils.

I'm getting quite frustrated by this. I found a method on the Roudybush website that I haven't used. It seems a little harsh, but I'm getting tempted to try it. This is from the Roudybush website:

2) Controlled. This method may be used with a very finicky, difficult to switch bird that is starting out at a good weight. It is generally the quickest, easiest method for switching most birds. Do not use this method on a thin bird, sick bird, or a bird you cannot monitor. Remove the old food and replace it with Roudybush. Clean the cage at the time of the switch and line it with paper. Do not use corncob or other litter because you won't be able to monitor the droppings well. Watch your bird's droppings or weigh your bird daily. When a bird isn't eating, the droppings will be very small and the green part will be very dark green, almost black. Or you may see a lot of urine (liquid) but almost no green part, which means your bird is filling up on water and not eating much. Give nothing but Roudybush for two full days for small species or three days for larger species. If at the end of this period your bird's droppings indicate it isn't eating, put your bird back on its old diet for 7 days, and then repeat the switching process. Most birds will convert the first time, and those that won't switch the first time usually switch the second time. If you can weigh your bird, keep your bird on Roudybush unless it loses more than 3% of its body weight. At that point, put your bird back on its old diet for one week then repeat the switch process, weighing your bird at the start of the switch. Disappearance of food from the dish is not a realiable way of determining if your bird is eating. Most birds will spill the new food out of the dish, looking for familiar foods.

I don't know if I should try this. I'm tempted to, but I just don't like the idea of him not eating.
