Hi, I have had one rooster die already about a month ago. Now, I have two more infected birds. Its a stiffening that progresses from the feet up from what I understand. They still eat and drink fine and it took five days for the first rooster to pass. The chickens showing signs of this are now quarantined to one of the three hen houses. One is a silkie hen and the other is a rooster(unsure of his breed). The silkie was bought from a feed store this summer as a friend for one of my lonely ducklings. Both roosters hatched this spring. We have three hen houses and a large fenced communal area shared by geese and ducks with a little house for the ducks and geese. We also let them out into our backyard and they have access to the horse and goat pen. I have determined this isn't a genetic issue since the silkie is an addition to our flock. I am now wondering if I should give the sick chickens antibiotics or if anyone has any experience with this. Thank you . and happy new year!!!
