Ok, so here's the back story, DH used to raise chickens years ago before we met. He got rid of them after hurricane Katrina when they stopped laying and he got busy. I grew up on my sisters ranch in Oregon where my daily chores included letting the chickens out of the coop, feeding them and collecting their eggs, so naturally when I moved in two years ago I knew we would eventually get more chickens. long story short - made him tear down the dilapidated, hillbilly looking coop. built a beautiful new coop. Its gorgeous, went out and bought some beautiful baby chicks. I've got five that are about 2 months old and two that are about 1 month old. I've just had their bag of feed just sitting in the coop for the moment. have been planning on getting a large lidded bucket to put it in, but they are not messing with it and for the moment the bag has been fine where it was..... well, two days ago DH tells me that he thinks he has a bucket in the shed that he used for his chicken feed and that he'd get it out for me. I didn't get out to see my girls at all yesterday because of a busy work schedule so I left their care up to my (supposedly) capable DH. When I went out this morning I found that DH had dug the bucket out of the shed, and it apparently had a good amount of old (possibly 5-7 years), moldy feed. He apparently broke up the moldy chunks and mixed my half-full bag of fresh feed in with it, and........ FED IT TO MY GIRLS!!!!! How concerned do I need to be about this? When I was growing up, I remember a truckload of hay getting moldy and my sister wouldn't feed it to the horses. I don't remember exactly what she said would happen, but I remember, it would have been bbbaaad. What might happen to my chickens and what do I need to look for?
