Richard from Winona writes
The Knock Out Ant, Flea and Tick Killer Granules should be watered in immediately after the application. Keep any kids, pets or animals out of the area while applying and until the watered in application has dried. This can take up to a few hours. Once the granules have dissolved or settled, it is safe for your animals to return to the area.
If the chickens ate the granules there is a possibility it can harm them. Please contact Pennington directly on their website or consult with your Vet.
