How do I tell if my chicks have cocci? I have lost two out of 15 so far. They hatched on the 15th or 16th, the feed store got them on the 17th, I picked them up on the 18th. One was very weak the first day and died the first night we had them. One of my EEs looked fine yesterday but was looking weak today. I had cleaned its vent twice, though it didn't seem to be terribly pasted, I just wanted to make sure. I went out to run some errands and picked up some poly-vi-sol to give to it, but by the time I got back, it had died. None of the others seem to be sick in any way. but I am wondering if I should put some vitamins in their water just in case. Can I do that and if I have a quart waterer, how much poly-vi-sol should I put in? I don't know why the two died but I am wondering if maybe they had cocci. How do I tell if the other chicks have it. I haven't noticed anything odd with their poop that wasn't something my other birds had when they were chicks. I have seen an occasional brown foamy poop, but then I will see the same bird have a totally normal looking poop, so I don't know if I should be concerned about it. What should I be looking for? Thanks so much for any advice!
