A few days ago I was asked to go rush to my second job and I was supoused to get the chickens feed that day ( I was out). I had only a hour to get the feed ,feed them, water them, get dressed and go to job. so in a rush I just took out of the car the cracked corn and just gave them all that. When I got home founded the smaller ones (3 weeks) with pooping blood...and dying one after another. I ran to check the other chicken and found them looking ok and just one drooping looking a little bloody (they are 2 1/2 months old) That was 2 days ago and still has blood in the droppings. I'm scared that I loose that one too. I think there is a problem with the corn or a problem of lack of grit....anyone know anything about it? What can I do? HELP!!!!
