Hi, I'm new to raising chickens. Today I bought 2 black australorps (<-spelling?) chicks and when I got them home and put them in their little space with heat light, fresh bedding, water and starter they looked "tired". They didn't cheep much and just laid face down. One died a few hours later and the other one can barely walk and will fall and lays on his face and I'm really afraid she will die too. What should I do? Do you think they were sick when I bought them? I'm going back to the feed store where I got them tomorrow I just don't know if I can bare to watch another little one die HELP!
