During the more frequent heat waves we have encountered in Michigan this summer, the girls are partial to summer treats -- frozen blueberries, watermelon and their usual banana. Spinach and lettuce -- poo, only if they must and I simply do not offer any delicious sugary options. It is clear they only eat it as a last resort. They attack their fruit treats with aggressive gusto, pouncing on pieces and running to a different area in the coop to make sure no one steals their treasure. Sometimes it's a little disturbing to watch. Equally disturbing is their enthusiasm for eating eggs. Cooked or raw. I still have a hard time with that one.
I discovered through reading Fresh Eggs Daily that you can provide cold water for them to drink (I would not have assumed it safe at first blush) . So on these steamy days I fill a tray with iced water; they spend several minutes sipping.
As I've said I like morning feed the best -- everyone is calm, relaxed and pleasant to be with.
Just be forewarned. If you stop by to visit, make sure you have a banana or two and you'll be greeted with open wings.
