Stock to be devel- oped for breeding purposes must be allowed and even encouraged' to use the wings enough to coun- teract the tendency to atrophy through disuse.'' The tendency to fatten, most desirable in stock bred for the table, is directly opposed to the continued production of eggs. A degree of fatness may be main- tained with great prolificacy and breeding power, but the general tendency of breeding from birds that fatten readily is to reduce egg production and fertility. Unavoid- able and troublesome as such con- ditions are, the difficulties they present may be overcome by selecting as breeders individuals which show, with the fullest development of form, considerable activity, and by properly differentiating between methods of managing breeding stock and stock not to be used for that purpose. ^ In such heavy breeds as the ]?rahma and Cochin, the difficulty that some of the birds have in flying to ordinary roosts two feet or so from the ground leads some breeders to discard roosts and bed the birds on the floor. Invariably the stock of such breeders will, after some years, become conspicuously deficient in breast. A fowl that, when in health, cannot fly to a roost two feet from the floor ought never to be consid- ered for breeding table poultry. 2 This does not necessarily mean that the bird should have the oppor- tunity or develop the ability to fly high. Byfiappingthe wings, by using them in running, and by low, short flights, a bird may give its wing mus- cles enough exercise to maintain Fig. 492.
