I have had this bird since March 12th. I had her since she was a chick. I have had no other birds come into the flock she has not already been in contact with since being born.
However, I had a Silkie pullet (6 months old) pass away early May from what appeared to be Wry Neck (she was healthy and within 3 days of moving my 8 week old chicks into the coop got Wry Neck symptoms and died 2 weeks later after lots of treatment), then on June 21st my husband randomly found another pullet, a Lavendar Orpington, (same age from same hatchery as the WCBP) dead by the coop door (no signs of sickness) and then July 7th we had the same thing happen again.. dead by the coop door no signs of sickness at all. Our weather has been all over the place here in WI going from mid 70's to high 90's within a weeks timespan back and forth.
I started treatment for Cocci with my flock that is in the coop that doesn't appear sick but simply for precautions. They appear healthy, eating, drinking, and stool seems healthy. I have checked for worms and mites with no sign of either.
I have been seeing small improvements with the WCBP but then I feel like we are good for two days and then down hill for a day or two. This has been the case for 1 week. I am willing to humanely cull if needed, however it is not what I would like to happen. I am also concerned about my other girls and what might happen if I want to expand my flock in the future once things are under control in the future.
