Hi laeeq aslam!
On BYC, many of the folks trying to help tell you figure out what breed of chicken you have are from foreign lands, such as the US, and they are not familiar with the type of breeds not from their country. Even the same breed from different countries can look different--Orpingtons being one example, so it is most helpful to get information from locals when possible.
It is very unlikely that the chickens you have are Easter Eggers. Easter Eggers are cross bred chiclkens that have some Araucana or Ameraucana in their ancestry. They usually lay blue eggs, have willow(green)-colored legs, a beard and muffs and a pea comb. Yours do not show any of these signs. What's more, since these breeds are from the US, it is very unlikely they have been imported in to Pakistan.
Wikipedia lists these breeds from Pakistan:
I did a quick search for chicken breeds in Pakistan and did not turn up many resources for you. Here is one resource that lists a few breeds:

The Desi is one they say is a non-descript ( generic-looking, or has a variety of different looks). I found other references for Desi goats. I suspect that Desi is a common name for a village fowl or animal or what we would call over here in the states as 'barnyard mix'. They most likely have several different breeds in them and over time have developed their own look (for more information, look up landrace breeds for a definition of this kind of genetic selection and breed type-- this chicken breed may be a kind of landrace breed common in Pakistan). The reason I think this is that you have said that everyone has this breed and it is common in your area. I suggest that you talk to some of the people that own the birds and see what they call them. Perhaps ask them if they are Desi chickens.
I may be off-base on my statements as I am making some assumptions. I am just trying to help figure out your puzzle. More information about the chickens you are showing us would be very helpful. Please let us know if you find any information from the local owners! Good luck!
