I just checked my chickens and found a hen that was laying on the floor. Her body was sideways but her head was up straight. My chickens usually do not let you touch them but I picked her up with no resistance. I placed her on a table and she did not seem to be able to stand. I could not find any injury. She appears physically fine. After a thorough investigation I put her back with the others and she clumsily went into a corner. In my books it seems like botulism poisoning, but it said they should die within 24 hrs. Yet I noticed a hen 2 days ago not on the roosts at night but on the floor by the nests. She was in a dark nook so I thought she might just be broody. Now I think it was this hen, which means this has been going on for atleast 3 days. What could it be? I am not particularly worried if I need to loose this one. I really just need to know if I should dispose of her immediately for the others saftey? Or can I let it play out and see what happens? Is this a disease? poison? Help! Thanks.
