Show experiments IN incubation results of serle series of tests made with hatching eggs by the pennsylvania station at the pennsylvania station a series of expert experiments men to in incubation were conducted from which the following conclusions clu were drawn under natural conditions eggs not promptly incubated are subject to dally daily worming warming by contact with the hens body which appears to have an important influence on the life and vigor ot of the embryo chick warming for 60 minutes givs s better result than for 30 or eggs held for incubation gh ga better results when laid flat and and turn dally daily no 40 especial difference due to position t was noted in eggs hold held for less than 16 to 18 days in both tests poorest results were secured with eggs placed on end and turned dally daily as compared with eggs laid flat or placed on oil either end and not turned influence of cf age of eggs on hatchability varied greatly presumably due to season or conditions of breeding pen washing eggs tor for lint hatching ching materially reduced hatchability eggs placed on end in incubator for arst tareo days daya ot of incubation suffered no perceptible injury eggs turned twice dally daily generally gave better results than those turned once dally daily |
