How to make organic weed killer at home?

I'm like [USER=63]@srinivas[/USER] & have removed manually. Another option if it's feasible is to get chickens or other fowl that would naturally pick off the insects.
I've used Castile liquid soap with Neem oil with success. I've also sprinkled Neem powder around plants. I also use it to rub in my pets fur as well lol If they are not flying insects like ants, Diatomaceous Earth works great. Sprinkle a nice circle around the plants. Downside is, it has to be kept dry so have to reapply it. Note: This is not the Diatomaceous Earth found in pools. It's made from fossilized remains of diatoms.

Ive had hens, but they spoil plants so kept them away also do they are harmful for our plants? You have lots of experience and here I am thinking to remove only unwanted plants that are growing again and again.
There are no insects also they can be removed easily. Thanks for your advice.
