Please help! After asking area 'experts' I have no solid lead on what to do. I have always had a great flock with no issues. Great health, great layers. I have a good knowledge of the do's and don'ts and spoil my girls with a rich diet of mash and garden veggies along with their usual pellet diet. The coop and run are much larger than needed, plus -they free range on a nice 13 acres- grass, woods... etc. Clean area. This past spring we added 8 hens to our group, 2-4 month olds. My mom also bought from the same two farm suppliers to BEGIN her flock. Not far into the spring/summer, we both randomly started to lose a hen- every few days... or after another week... and still. We are down a total of 6 hens total. I can only imagine that the new ones brought something in! Problem is... they seem to die without any warning. We go out to do something (morning or night) a we find one dead. Its very random. Only one -my sweet baby girl, Kimmy, showed signs for a few days. SHe held her wings low, was unable to roost/jump up... she was wobbly when you set her down as if her legs were unsure. But no others act AT ALL in distress! Combs, feathers etc...fine! I can't see worms, but just gave them Wazine the last week to attempt a treatment of some sort. What would invade my flock and cause sudden deaths? What do I look for? What do I do? Please help!
