Hi.
Like a pigeon world, I know finch need to use vitamins, parasite control, lice and mite, some antibiotics, bath salt and many more product to have a good health. But they are many differences products in the market.
What product do you use frequently?

These are good?
Vitamins-Breeders Blend, Calcium Plus, Hearty Bird,
Parasites and Worm control - Worm Away
Red mites - S76
Antibiotics - Tetratex

Thanks.

Breeder's Blend is a derivative of Hearty Bird so if you preferred to only get one multi-vitamin I would probably recommend getting the day-to-day one which is Hearty Bird.

Calcium Plus is great and also nice to have on hand in egg binding emergencies.
S76 is more for Scaly Face Mite and Air Sac Mite, not red mites.
Worm Away is good
Tetratex is a good broad spec but it is very potent and very much geared towards chlamydia/ornithosis, I think a better broad spectrum antibiotic would be Trimethoprim Sulpha or a multi-use drug like Med-Pet's 4-in-1

Hi.
Where i can buy this one, Med-Pet's 4-in-1??
Thanks.

I get it from www.birdsupplynh.com
