Ok, you problably don't need or want anyone to say this, but I have to.
If any of you see chicks in bad situations, don't pay the people for the chicks, don't do business with them. It's JUST ENCOURAGING BAD BEHAVIOR! If it was kittens or puppies in a sealed plastic box, someone would of called animal control and they would be charged with abuse or neglect. Farm animals have no right to be abused in this way.
Now, I am not some fanatic vegetarian, but it seems to me, that this person went home thinking of the money they made, and that they did nothing wrong, while you are shelling out money for dying babies. They will go back again next week with more chicks in a sealed box, and some sucker will pay them again! Stop the cycle!
OK sorry, had to get that off my chest. If you see them neglecting or abusing, tell them this is not helpful to the animals (in your nicest voice) and let them know you won't be buying animals from them until they change. It worked at my feed store.
