99% of all pellets on the market, the first ingredient is corn. Corn is a filler with poor nutrition.
We are especially happy with Nekton Vitamins. They should have everything that you might like to add.
Nekton-S Multi Vitamin is a very good multi-vitamin.
Nekton Bio would be fuel for the feathers.
I hope this helps.
A timer set for 12 hours on and 12 hours off daily with a good full spectrum bulb above the cage top (just out of reach of the birds) will help keep them evenly keeled all year round.
It is a strong possibility that one or both of them are feeling frustrated and you can see it in the feather picking pattern in the one.
By the way, the area is likely in the front and up and around the neck where it can reach them. Is this correct?
So, we have a very good solution for that. Totally free and completely safe.
This also works for broody and egg laying females and even works for horny male birds who are just a little too testy to handle anymore.
A 72 hour light treatment.
Instead of covering their whole cage at night you will wrap around the cage and leave the top exposed to the light.
If you have a play top cage with a tray, get rid of the tray.
If you must have something up there get a clear plastic cutting board or something, but no more solid top.
What this light treatment does is reset the birds circadian rhythms.
Then when DST comes, it is then 7 to 7 without touching the timer.
Please mull this all over and let me know your thoughts, if you have any questions.
