OK, I have found 2 chickens dead. One was a baby about a month old and it was with its mom, and the other was a silkie hen about 2 years old. This happened 2 days apart. Both seemed very healthy the morning they passed. My silkie hen had just started to molt. I found the baby on top of the nest boxes almost dead and I tried to bring him back to life. I found my hen under a shed. She was not the mother of the baby. Neither have any marks on their bodies, no feathers missing, nothing. I do have black widows and brown rocluses here. I know they will do a number on a person but will they bother a chicken? What if they eat them? These chickens are my pets so I need to find out what is happening to them.
