Adults known to have wet and dry fowl pox. No signs in chicks 4 have dropped dead in 2 days. Walked on 5th one laying down to die. Wrapped in a washcloth in my hand. Keeps having almost a seizure - extending legs and throwing head back over her own back. Gave her liquid b 12 and contents of fish oil capsule in hopes it may help. Leaving house in 1 hour for meeting I can't miss. Started coccidiosis treatment for flock with corid yesterday evening just in case. vaxing for fowl pox this afternoon. What else can I do? What do you think this is. They are fine till they drop dead. I see a couple things under wings that might be pox lesions and one side of her tongue has maybe a white patch.
