Why egg prices HIGH in WINTER

Why egg prices HIGH in WINTER
I do not understand SAME egg which is under Rs.4 to 5 single egg being sold during SUMMER season AND now Winter is begin but not reach its peak now egg being sold Rs.9 each ( see the difference )

I have observed egg prices cross Rs.10 each during December & January Winter seasons it means now Egg Traders turn to earn money no matter by abnormal profits all are allowed and acceptable.

Why Govt always remain silent and do not control the prices when ever any traders who caught selling above the Govt prices than immediate basis fine but sorry Pakistan is the country where no LAW EXITS first and no one worried to follow because no fear of punishment.

Think for poor and middle class families who have large number of family members how they force to manage and bear the additional expenses in the name of abnormal profit or inflation ( but for all these circumstance he Is not responsible for facing)

Why in summer same egg being sold below the Rs.5 the reasons behind consumption is reduce and more fear of lost of hen/egg due to hot weather but in winter prices almost double? Which indicates that Pakistan is heaven for traders in which products being sold by traders wishes prices not ever followed by Govt uniform prices but in this regard or issue Govt ever seem serious how to control the prices.

Thanking You

Yours faithfully
