Hen after deworming is lethargic, doesnt eat and not laying eggs

[LaFleche]

Update: Since yestarday shes way better. Walking with others, digging, eating every food I offer her and drinking. Her vent is not swollen anymore. She is not laying eggs yet but I think i have to give her some time. I Think she was ill becouse of dead worms in her body. Thank you all for helping me

I love good updates!
