I know that sounds funny...but yesterday we finaly got our babies in. Here once it gets dark we have a ton of those little moths that are about 1/2 in long and very skinny that come out. Well I was watching the chicks since one if a little weaker then the rest and saw one of those moths fly in there. It landed right in the middle of the chicks. They went nuts over it pecking it running with it, it was so cute to watch. After almost 3 minutes of this one finaly was able to swallow it. So I am wondering if they are going to eat these moths do they need grit or not. It was just that one tiny moth but I never know when one is going to fly in the house and it seemed to love there light in the brooder, which makes me think there might be more. I was planning to put grit in there brooder at about 1 to 2 weeks old. LOL..I sound like a worry wort.
