What is the name of the feed they don't like? Our new hens arrived with an unopened bag of feed that smelled very different than what we have. Nothing was wrong with it; it was just very different.
I feed them H and H layer crumbles when u get home this evening I will post a picture of the tag on an empty bag we have
The plastic trash bin and lid should be washed and dried before using. I always air my new plastic containers of any type for a day or two before using (until the plastic smell is gone).
