My wife raised Small Birds and was real proud of her operation, until, I purchased a Kerosene heater, worked real good, if careful I could move it around safely, well the utility room was getting cool so I moved it there and it worked real good there also, birds liked the heat until I turned it off, well you all know they emit an odor when shup down. Bingo, I put her out of the bird business in about 1 1/2 minutes. If them heaters killed all them birds(over 1,000 of them)they can't be good for us, go with a vented heater.
