combining chickens and vegetable garden

...and if you are going to do rotational grazing, look into rotational planting as well. Legume - Root - Fruit - Leaf - Repeat. Which really means 6 sections, not four, so you have one for the chickens, and one being prepared for the new planting.

Our idea is to have free range chickens in a fenced block for some weeks until they clean it from the weeds and then start our own vegetable garden in the same block. Since fresh chickens manure is very strong and can kill the plants, do you think we should wait until we plant or do you have any other suggestion how we can facilitate the maturity of the manure?

It would depend on the amount of manure (which is affected by the amount of space, and how many chickens, and how long the chickens were present.) You might be able to just plant right away.

In a warm or hot climate, you could certainly plant within a few weeks of moving the chickens out.

The easiest way to know for sure is to try it. Maybe move the chickens out, and plant a small amount of each crop right away. Then plant a little more of each crop once a week. Make notes on how well each crop does. You might find that some things can be planted immediately and others need to wait a few weeks, or you might find that everything can be planted right away, or everything after two weeks, or something like that. But you should only have to do the experiment once, because after that you'll know the answers.
