Does anyone know if any medications have been used in the form of Transdermal Gels for birds?

I've heard rumour of a new transdermal worming gel from a reliable source. Need to find out more info. but when I do I'll post about it.
I crop worm new birds and the transdermal gel would be so much less invasive. I use chilli for maintenance.

Wow! Transdermal gels would be awesome! Of course, you still have to get it on the bird. Transdermal drops like the flea preps for cats and dogs would be great as well. Give it time and I'm sure new things will come about.
