Bless you for jumping out at that intersection to help that poor chicken! I really hope that there is a special place in heaven for those who rescue animals....Last year I rescued a runt of a chicken with a scissor beak and blind in one eye, from my neighbor. I named her Lucky Lucy, but one day, she crowed and from then on, he was Lucky Louie.
Because he was a rooster, he was picked on by my little white banty rooster, Fancy Pants, and then then other chickens followed his lead and I had to keep him fenced in the yard when the others were free-ranging, and in the chicken house he was with the flock, but in his own little chicken run.
He had so much going against him, but he always seemed so content and happy. He loved the warmth of the sun and to sit on the front porch steps watching the world go by. He came to me when I called him and he just loved to be petted. But it was hard not to feel sorry for him watching him eat because of his misaligned beak, and with only one eye, he didn't have any real depth perception, so I had to use a really deep casserole pan and fill it to the top so he could just stand in his food and bury his beak in it just to get enough to eat.
To make a long story short, by the time he was 6 months old Louie was HUGE in size and a few months later, he developed a number of growing tumors all over his body. He didn't quite make it to a year old. He died one night, and I think that it was probably a heart attack.
But he made me so happy just by being so happy himself. He never seemed to notice his handicaps and enjoyed each day, I think, til the very end. I enjoyed every day he was with me and he was one big reason why I became a vegan. Best decision I have ever made. Ever.
Light and love to you and your rescued chicken. Enjoy her and share her experience til the end of her days, whenever that may be. It will change your life:0)
