my chicken indiana is all of the sudden looking sleepy and lethargic and i dont know why! all she had earlier were some grapes maybe 3 at the most but more likely 1 or 2 i dunno i fed it to them but i cant exactly remember! she keeps jutting her head forward oddly and she is extremely tired every time she is still her eyes close and she looks sleepy and all the other chickens are away from her... i dont know what to do she looked fine not 3 or 4 hours ago! i have know idea what is wrong the only recent changes to our schedule were the snack of some grapes which i fed her last week and she was fine and the fact that we have june berries (strawberries and blueberries) that they kept eating b4 they were ripe so they havent been able to run in the yard for the past two days! HELP ME PLEASE EVERYONE IS BLAMING ME JUST BECAUSE I WAS THE LAST ONE TO C THEM!!!
