I have 5 chicks coming this week (three splash marans, and two buff brahma). All is set up for them, but am wondering if I need to buy new food. I was going to, but husband found 3/4 of a 50 pound bag of chick food left from last year. It has been stored in our house. He thinks it would still be safe to feed the chicks. I am wondering about the age of it. When does food get too old to feed or be safe/healthy to feed? Since he is retired now and we are on a limited income, he would like to feed the stuff from last year and it really would help to be able to do so. We don't get much money to live on.
