I found a dead chicken inside the coop. The strange thing with it is that she was really vivid the last few days. I saw no evidence of the tape worm infection on her, she had no parasites on her feathers and her weight was normal. What i thing could be the reason for losing her is one of the following or a combination: 1) Too much heat. It is pretty warm here the last couple of days. The temperature is around 30 C (90 F) in the shade. So i guess in the sun it can be a couple of degrees more. 2) In the last few days i found blood stains on the eggs. One of them had quite a lot. Could it be her last egg? 3) The tape worms killed her. Even though she had no symptoms. 4) The rooster? or another chicken? killed her?
