When to start deworming?

[Sussex19]

And @dawg53 I'm really not trying to argue, so please don't think I am.
I just have my own opinions on things, and I know what works for my flock. I just wanted to give the OP a few more options, so they can work out what works best for them.

But did they though?
We have got a fairly old book written by a very well respected man, who didn't worm is chickens.
His laid for many years, and would have lived for many more if he didn't put them in the soup pot.

Alot of people say that.

It's your environment and soil conditions that dictate how often birds need to be wormed.

Perhaps you would like to host a few worms and tell us how you feel after a few months.

No thanks. I can do without.

P.S. couldn’t find the research of WuR. Maybe the report was in Dutch or maybe it was a Louis Bolk institute report.
I found one interesting report though. In chapter 6 you can find info about parasites in free range organic chicken farming:
