I wrote to the vet that I would like to take my bird for an examination. The vet wrote that he will not be at the bird hospital in the next week, so we will consult. I sent photos about my bird to him on the Facebook Messenger. He wrote about my bird that her beak is very overgrown, her eyes and her feathers are not okay, she looks very bad. He asked a few questions, then he recommended two things.
Agroferm M+C, Vetri DMG.
He wrote that I can order these online, and that the first will be enough for starter.
Before ordering, I checked the local stores, but they are not selling these. I already ordered 100 gramm Agroferm M+C online. It is 2798 Hungarian Forint (HUF) ($7.85 USD) with shipping. 1 USD is currently 356.65 Hungarian Forint (HUF).
The Vetri DMG is more expensive. 30 milliliter is 9499 HUF ($26.63 USD).
Of course later I will order this too. Probably I will receive the Agroferm M+C in the next week.
The vet also wrote that I should give meat with bones (not just/only meat alone) to my bird. And that the calcium tablet is not necessary in this case.
I will talk to the postwoman. Her husband is a hunter. Probably they can get entire prey animals (pigeon, quail, rabbit).
If I will have news, then I will write about it.
Have a nice day and have a nice weekend.
All the best. Greetings and much love from Hungary.
