my 1 year old died last week, today my 6 year old chicken died today, showing the exact symptoms. they both had diarrhoea, not eating and very wobbly, they sat huddled up and sleeping all the time with beak on the floor almost as if their head is to heavy for them to hold up. does anyone have any idea what this can be, also they felt hot. they died within 48 hours from showing symptoms of being ill. no mite problem. both have been wormed. crop was fine until they stopped eating. not under weight. worried about my other girls now, is this contagious.
