One of the other things we had to be extremely cautious about was cleanliness for people going into the barns and all that. As a matter of fact, strangers were not invited in, period, and it was only the people who had to actually do the work in there who were in the barns. There's no tourism, if you like, because it's an absolutely clean environment.
With regard to the type of chick or pullet brought there, are they a particular breed that is resistant to some of these diseases? I would think that it would be difficult to control the environment if you don't have electricity and you don't have the air conditioning and other things to create that clean environment. Is there a particular breed that you use?
