Hi, im new here & desperate for answers as to whats killing my chickens! Two young hens seemed healthy & normal up until 24 hours before their deaths about 3 weeks apart. One had previously been ill & laid some shelless eggs but had rallied & was well again ( although she never laid again). Untill their deaths the birds seemed in good health, no bloody poop etc. The other hen laid eggs until the day before she died. What would kill them so quickly? I feed them the best of everything & we have another 2 laying healthy hens. Unfortunately I didnt worm them from point of lay for about 3 months. When the first one died I was told to worm which was about 1 month before the second hen got sick. Could it be worms? I just dont want the same thing to happen to the others, my young son is Devestated! Any advice?
