I HAVE 2 AFRICAN GRAY GEESE, I HAVE HAD THEM FOR ABOUT 2 MNTHS NOW, EVERYTHING HAS BEEN GOING WELL, BUT TODAY I FOUND ONE OF THEM HIDDING IN A STICK PILE, AND IT WAS SLEEPING, IT HAD NO ENERGY, IT LET ME PICK IT UP, IT HAD WHITE STUFF COMING OUT OF ONE OF ITS EYES, I PUT IT IN A CAGE WITH HAY, WATER, AND FOOD, AND HEAT, ALL IT WANTS TO DO IS SLEEP. ANY IDEAS FROM ANYONE, WHAT MIGHT BE WRONG WITH MY GOOSE?
