Teflon fumes can still be a problem even with ventilation - especially in a brooder where the lights are relatively close to the chicks. I know people who have lost parrots from PTFE fumes when the birds were several rooms away from the kitchen. Granted those were teflon cookware fumes, not light bulbs, but it's the same toxic gas. Birds are ultra-sensitive to it. I wouldn't risk it in a brooder.
When I first heard about this PTFE fume issue 15-20 years ago the Teflon cookware folks wouldn't even acknowledge there was a problem. Now they put warnings on the cookware. It's in tiny print and it comes after all the "nontoxic" statements, but most of the PTFE cookware labels now admit that the fumes will kill birds if the cookware is overheated. Maybe they'll start labeling the lightbulbs, too. BTW, "overheated" isn't all that hot. I think the fumes kick in around 450* F in the cookware. Not sure about the lightbulbs.
Speaking of heat sources, does anyone have a good source for ceramic heat bulbs? I need some backups and my old supplier no longer exists.

Man! I wonder what that (PTFE) puts in my scrambled eggs then LOL no wonder I'm crazy as loon sometimes LOL
I got to remember to use those old black iron pots/skillets more often, they say those are bad for you too but I know they only got lard(bacon drippings) in them to keep my eggs from sticking to the bottom of the pan.
