I came home today to find my silkie 3 mo. chick and 2-10 week old Eng orps dead. I noticed Friday evening some blood in the shavings. I wormed them just in case (which i do monthly anyways w/ DE). When I found them this afternoon I immediately cleaned and disinfected all cages, feed bowls and watering containers. Put new shavings in and then I saw one poop and it was blood. SO..I went into panic mode. Read on a thread here it is Cocci. I have isolate 3 silkies, one I saw poop and 2 that had blood on their fluff around vent. We have had hot, humid and rainy weather for 2 weeks. I have a fan in the hen house room they are in with windows and doors open. I had my DH go get Corid..but a friend of mine is telling me they need antibiotics....but I have then on medicated feed since hatching. Or do they need both? I also had him get yogurt and powdered milk. So...I need to see if this is correct or if there is something else I need to do. It is going to be a huge loss if I lose these babies..a huge heartache. Thanks so much!
