My husband and I purchased an older house and it uses propane as a heat source. The heat comes from wall units much like this one; there is one in each room. I am GUESSING that these are not bird safe as a quick google of gas heat sources suggests it is dangerous for birds. Frankly it worries me anyways as I don't love the idea of funneling a bunch of flammable gas into my house; too easy to make a mistake. But, can someone confirm the safety status of propane for me? My second question is this: are there any bird safe plug-in electric space heaters? I think I read that some have coatings that are not safe for birds, and others are safe - but I don't know how to tell the difference. However, we saw some plug-in baseboard units at Lowes that looked like just regular old heating coils. Potentially safe? I'm asking because we are uncertain if we can get electric heat this year due to some unexpected financial constraints that have arisen due to problems with this house. If we can keep the birds warm and safe this year with a $100 heater instead of a $4000 overhaul of the house's heating system, that would be ideal. Obviously if the ONLY way to safely heat the bird room is to install electric heat, we will cry over the corpses of our wallets and get it done, but if we have an alternative for this rough first year it'd be great.
