I think my small flock of 22 week old mixed breed chickens may have drank some water 2 days ago containing some bleach. They seem to be depressed & are drinking lots of water, not as much food. Poop is watery,one of 3 roosters (white leg horn) the head guy is not crowing during the day and only about 3 times this morning.(sound is not the same) Liquid has come from the mouths of a couple of the birds. The only other exposure they have had may have been to fire ant bait in the yard, as they roam the prop. for a few hrs daily. It had already rained for 2 days before they had access to the fire ant bait, and only a tiny bit if any in only a few spots on the 2 acres they roam. 2 birds seem unaffected. The water containing the bleach was very diluted, but these are the only things out of the ordinary that may be responsible for the sick behavior. What can I do ?, or what else could be the cause? Thank you in advance for the help.
