tl:dr -> Is it ok to give my budgies grated carrots every day?
I'm so happy that my two budgies have finally started eating vegetables but I'm wondering how often to give these to them. Every website seems to have conflicting information. Currently,
1. Grated carrots: every day
2. Broccoli, spinach, coriander, baby corn, kale: 3-4 times a week (each)
2a. Cooked sweet potato, peas and frozen (& cooked) sweetcorn.: 2-3 times a week.
3. Other veggies, herbs & fruits, sprouted moong: occasionally.
4. Egg: 1-2 times a week (yeah, I know, it's not a veggie
5. Vitamin supplement from the vet: every 2-3 days in their drinking water
Basically, I fill up two dishes with grated carrots and then hang the other veggies from the cage bars. I've seen them eat carrots (and the younger one at least tries everything else as well) but I don't think they really have large quantities of any of the veggies. E.g. if I didn't see them eat carrots, I wouldn't be able to tell because the level of carrots in the dishes doesn't really seem to reduce. The younger one definitely has large chunks of baby corn though whenever it's in their cage, probably 1/3 of a baby corn. The younger one nibbles at the other vegetables but in very small quantities (e.g. a few tiny bites of a spinach leaf)
On some websites I've read that you shouldn't give carrots every day but broccoli is fine daily and on other websites I've read the exact opposite. I know that humans can overdose on some vitamins such as vit A (even if it's unlikely unless you are taking supplements) and I think you aren't supposed to give too much of spinach or basil to budgies as it binds calcium. I just can't figure out what is meant by too much, especially considering that they are also getting a vitamin supplement.
Initially they weren't eating any veggies and the older ones beak looked quite unhealthy, which is why the vet suggested the vitamin supplement. I'm slowly reducing the frequency of the vit supplement from daily to just 3-4 times a week now. Should I stop it completely now that they are eating veggies?
Also, how long can you leave the veggies in their cage? I usually put them in their cage in the morning and leave them there for 8-10h till I return from work (on weekends, I change them every 4h). Somewhere I've read 24h and somewhere else just 2-3h. It's not too hot at the moment, about 18C.
Also, are these safe and how often can I give them:
Sugar snap peas
Any other vegetables/fruits you'd recommend that are either super healthy or that your budgies absolutely love?
