16 HOW I MADE $10,000 IN ONE YEAR 



the mixture we use, described in the chapter devoted to 

 "Cleaning and Disinfecting." Cover every inch of that 

 old building with this spray, inside and out, up and down 

 and sidewise, and when you are through and have done 

 a good job of it, go over it again. Five days later repeat 

 the dose, and then you can feel that you have taken every 

 human precaution against falling heir to trouble. It mat- 

 ters not whether there ever was a chicken within 10 miles 

 of the place, or if there has been nothing in the building 

 for as many years, spray it as herein outlined. 



The question of yards and yard space is a much mooted 

 one. Some people advocate shutting the birds into a 

 house or coop and giving them no yard space at all be- 

 cause yards are disease breeders. This seems to the 

 writer to follow literally the biblical injunction "if thine 

 eye offend thee, pluck it out." We use yards and believe 

 they are conducive to the health, well-being and happi- 

 ness 6f the birds and we enjoy their seeming enjoyment 

 of that much freedom. 



Wallowing in loose moist earth seems to be one of the 

 habits we cannot break biddie of, and there is grave ques- 

 tion if we could afford to do it were she willing. There 

 is this to be said, however she is better off with no yard 

 at all than to be on soil baked as hard as a brick and dry 

 as a bone in summer and a mess of sticky mud in winter. 



Ninety-nine out of 100 poultrymen, including so far as 

 we know, all the experiment stations, give their hens 

 more or less yard space and your safest course is to fol- 

 low this lead. You should allow enough space to each 

 house so that you can shut off a part of the yard at regular 

 intervals and freshen the ground by growing something 

 on it.
