I read that citrus is not good to feel your flock. Ok - why?? We're newbies and haven't even purchased our chicks yet. How about Aloe plants any idea if those would be harmful? We're about done with our coop and want to fence their yard. We also want to be sure that our future gals don't have any harmful temptations in their area..... Thanks in advance for any and all your helpful advice. It's greatly appreciated..
