Careful of grapes and other small round fruit (ie: cherries, or cherry tomatoes) as the birds can get blocked crop from them.Java's are so funny!
Our rooster, for some reason inexplicable to me, has determined that the water hose is evil, pure evil! And he chases all the hens FAR away from evil, evil water hose!
So today, I fill up some tinfoil pie plates (the disposable ones), as our chicks are tiny and I didn't want a kiddie pool drowning. I use these same pie plates to serve treats! So I place them strategically around the run in shady spots, favorite spots, etc......and fill them using evil, evil water hose.
They NEVER went into the water! Rooster kept them ALL far away from the suspicious pie plates. He REMEMBERED the hose filled 'em!
So, tomorrow am, I'm getting red grapes (chicken version of chocolate). And plopping red grapes in the water. It'll be irresistable! And I'll fill the pie plates with a watering can instead of evil hose!
They gobble the grapes up and the grapes never get chewed so can easily roll down and block the crop.
I have lost a few birds this way.
Chickens have no stomach acid to digest, nor teeth to chew, so the grape rolls right down...be careful.
