First time with new chick's. Ordered from Murray McMurray. Came this moring. Ordered 26 birds. 3 of them that were the sickest were white crested bantams I think. I was dead on arrival. One died in 30 minutes . One now sick. Lethargic and won't walk just like the 2 that died. Won't hold up head except when we help it drink it puts head up to swallow. Looks like bubbles coming up is throat almost like having a hard time breathing or swallow. Now 2 other birds look like have bubbles. I separated them. They have sugar water and electrolytes/vitamin mix added in their water. Also raw apple cider vinegar. What is the problem and is there something I can do to help or is it a lost cause? Thanks so much.
