So, I went outside to get eggs and give my girls grapes. They have had them loads of times, they love them! Anyways, I fed them the grapes and gathered the eggs. Then I notice one of my girls(Aviva) bobbing her head with her beak open. I tried to grab her but she has always been flighty. So I ran inside, yelled for my 8 year old son and ran back to the coop. He helped me corral her into the coop where I was able to grab her off the perch. I held her down onto the ground and pulled a 2 inch chunk of grape out of her throat! Moral of the story, from now on, I will be cutting their grapes into smaller pieces. Never even thought that chickens could choke...
