A quick and easy treat to help with the summertime heat waves is a frozen melon bowl. These are simple enough to make unless you want to be extra and make it gourmet...but I will keep it simple. First thing you do is halve a melon, watermelon works the best for this.
Scoop out all the innards and put them in a big bowl...then smash smash smash. Make sure the innards are now a nice pulp filled slush.
Dump this back into the melon bowl and freeze overnight. (This melon also has banana and chicken feed mixed in- but you don't need to add anything if you don't want to.)
Put it out for your flock as it starts to get hot out. This will provide a refreshing and interactive treat for your birds during peak hot days.
