I'm a new member at the forum - my name is Megan. I'm considering getting two society finches. I'm currently gathering all the information that I can to see if this would be a good decision for me

I became interested in watching and drawing birds this past summer. I've been visiting local pet stores recently to watch the birds and have fallen in love with the finches. They're so beautiful as they flutter about and poke at their food, water, and millet. I especially love the colors of the society finches.
I bought a book about pet finches so I could learn what it would be like to have some at home. (I've owned rabbits in the past, but I've never had a bird.) I think I have a good spot for them - it's a quiet place that's free from drafts still gets light. I've made a list of all the equipment that I'd need to give the finches a good home and checked to confirm that my budget could accommodate it. I don't travel much - just overnight trips once every few months.
One concern that I have is allergies. My father is allergic to cats and dogs, but I'm not sure if he's allergic to birds. I also have seasonal allergies, but I don't think animals are a problem for me. Do any of you have experience with finches and allergies?
Also, do you have any other advice for me as I consider getting finches?
Thanks

Megan
