1% deltamethrin - for cattle it's 17 days withdrawal for meat, none for milk, but hens I've no idea

There was no adverse reaction to 5 drops per bird and fingers crossed I can see some black spots on their baldy bits so it looks like new feathers may be emerging after 3 months trying everything else..
I will not use any eggs for 7 days from treatment minimum unless the person that recommended it on another thread says differently - might cook them up and feed back to the chooks tho with some rice or something if nobody thinks that's an issue?
Seems a waste of 4 dozen odd eggs to just throw them in the compost..
