This is the old question - whether egg has come first or the hen has come first!!... if there is an egg then hen will come out of it.. if the hen is there then only it can lay eggs.... we guess if there are 2 hens then only the possibility of an egg is possible.. if there is a single egg then a single hen will come out!!.. even if the single hen comes out then it won't be able to mate and get another egg out in this world.. and it has to be a female!!!........ Although stupid question actually it's not!!.. there has to be some answer!!...

This is actually a deadlock question!!...and both are dependent on each other!.. Technically speaking.. the same question can be asked for man and women... or for every other creature.. So we have to crack the theory of evolution.. Newton cracked gravity when an apple fell on his head so... you can also do the same.. and just comment on whatever logical comes to your mind!!..
