Seven Methods of Feeding Young Chickens. 549 



supply of energy — just the sort of chicks one would want to turn on 

 free range to be kept for laying and breeding purposes. 



Mortality: 



Greatest Flock 56 — Cracked grain ration — 22 . 7% 



Least Flock 61 — Variety ration 00. 0% 



Weight of flocks 



The weight of the flocks at the beginning of the experiment and 

 at the end of each week of feeding are shown in Table 5; also the 

 numbers of chicks remaining at these periods. 



Flocks 59 (powdered milk mash) and 60 (skimmed milk mash) grew 

 fastest from the start, making nearly twice as great gain in weight during

Fig. 172. — In total gain in weight during the first six weeks, the wet-mash and the 

 variety ration flocks were far ahead of the dry-grain ration flocks, and contained 

 larger numbers of chickens. (Based on Table 5) 



the first week as flock 61 (variety ration). It will be remembered 

 that this last ration was designed to give slow growth for the first 

 week or two. During the second and third weeks, the flocks having 

 the wet mash were still ahead in gain and in weight, but flock 61 (variety 

 ration) became heavier than any of the flocks having dry-grain rations 

 (55 to 58). Until the third week, this flock had been lightest of all, but 

 during the fourth week it made the greatest gain of all, and during 

 the fifth week it made the greatest weekly gain shown in the six weeks 

 of feeding. In total gain for six weeks, and in total weight of flock, 

 flock 59 (powdered milk mash) was first and flock 61 (variety ration) 

 second. For the first three weeks, flock 60 (skimmed milk mash) was
