Sorry, didn't notice that. It is an aviary.
I've tried to research wether the wattyl stuff is okay but I'm not having much luck. My dad has years of experience in keeping birds and he thinks they should be okay.
I just read on the paint can that the paint is suitable for surfaces used for water collection. If its okay for that, surely it'd be okay for birds. It does have a bit that says keep out of reach of children though. But wouldn't they all have that?
Help!?!
