Any way to use unscented candles?

I'm really fond of both doves and pigeons and have been dreaming about getting a pet bird (or two). The problem is, I'm Jewish and candles are ritually important. I know there are electric menorahs for Hanukkah, but we also light candles for Shabbat dinner on Fridays and the candlesticks we use are very sentimental to me.

I've seen conflicting advice online about whether unscented candles can be safe. Burning anything will cause a tiny amount of smoke, and it seems like the wax and wicks can also cause respiratory issues.

• Would lighting them for dinner once a week in a different part of the house pose a problem? Doors closed, ventilating the dining area afterwards, etc.
• Are there any other precautions I could take, or candles that are safer to use?

Obviously if I had birds their health would come first, but I'd like to be fully aware of the dangers first so I can make sure my home is safe. Thanks :)
