Emptying a few cans of corn into a muffin tray, adding water & then freezing it is a very small act of kindness for chickens. Pecking away at an ice block to finally be rewarded with a cold corn kernel is a great way to help them keep cool .
Mother Nature and Chickens have an awesome trick up their sleeve to keep eggs fresh. This trick is why I don't refrigerate my backyard eggs. CAn leave out on counter for 2 weeks or more. Freshness test if it sinks its fresh.
