About five days ago my hens started acting lethargic. This started after they were given lots of tomatoes (not the plants, the tomato scraps from a huge batch of sauce we were making) They also were getting huge armfuls of weeds from our property. The next day we noticed them all laying in the corner of their run and not coming over to us as usual. They normally run to the door to meet us for their next treat. This behavior has continued. They stopped eating any treat being offered and continue to lay around. They are not eating their feed either. Their poop is runny. Yesterday we only got three eggs and usually get 6 or 7. The shells on the brown eggs were extremely light in color and the shells thinner. Today no eggs and they are still laying around. I put electrolytes in their water. I went to pick up my favorite hen and noticed she was hot and her crop was very smushy. I dipped her beak in the water and she threw up all over. I gave them a head of iceberg lettuce which normally would have been gone in about five minutes and they hardly touched it. Their eyes appear normal as well as their combs and wattles. I don't see any discharge from their nostrils. I am a clean freak and the coop is immaculate. We did get tons of rain and their were puddles in the run for several days. The food is the same bag they have been eating for a month. I am very worried. Please let me know if you have any ideas on what could be happening. Any suggestions on what to do. Any help would be greatly appreciated. I am sick at the thought of loosing one hen let alone my whole flock.
