I have had 2 POL chickens keel over and die. They both were feeding, drinking and perching and gaining weight. de loused them 2 weeks ago but not wormed them how do you tell if they have lung  or gut worms

[muntjac]

you open them up and look inside the throat down to the stomach .check the liver for white spots or any discolouring at all , the hearts for worms

 if you suspect this i suggest you worm the rest of the stock .

There's no easy way to tell.  You may see worms in the faeces but only in a very heavy infection.  Lung worm will make the hens gape and struggle for air.  All of these signs mean a bad infection and treatment or rather prevention should be taken before symptoms are seen.  Look at the sticky below for full information:

Sudden death in birds can often be caused by heart attack or stroke.
