I think your doing the best you can. Plus, you are learning. As a parent myself, most of us want you to be happy. But, things beyond our control seem to stress your mom out. Try not to involve her too much. She has her own issues she's dealing with and you don't want her to make you get rid of your girls. Your dad seems to wanna help but, doesn't know chicken stuff either.
Be patient with them. Your doing a good job with what you have. You will use up the feed. Keep it secure and in a cool place to keep it from molding. Don't feed any other critters in your yard.
The hoop run is a great idea after you move.
