Annual report of the Maine Agricultural Experiment Station . tend to the most minute details ofstructure, perhaps not apparent to anyone not perfectly familiar 122 MAINE EXPERIMENT STATION. I9IO. through first-hand practical experience with poultry and par-ticularly Barred Plymouth Rocks. Thus the beak—which isnot ordinarily reckoned as a secondary sexual character—inthis bird is to the fancier unmistakably that of a male. The triple yolked egg shown in Fig. 82 was laid September27, 1909, by a Barred Plymouth Rock pullet bearing the leg-band number 318. This pullet was hatched March 29, growth and physiological development were normal. Dur-ing the spring and summer this chick was kept with others ina large field of grass, where it was under free range September i, 1909, this pullet, along with others, was putinto the poultry-house which provides permanent winter quar-ters. She began laying about three weeks after this removalto the house. Her complete laying record to the date of writ-ins: is as follows:. Fig. 82. Photograph (approximately natural size) of the triple yolliedegg described in the text. One egg was laid by bird No. 318 on:— September 21, 24, 25, 26, 27, 30. October 2, 3, 4, 5, 8, 12, 13, 16, 17, far as is known the first three eggs laid by this bird wereentirely normal. That laid on September 26 was soft-shelled,i. e., bore only the shell membrane as an outside covering, withonly a slight deposit of lime in the form of a true shell. Thiswas followed on the 27th by the triple yolked egg. Since thatdate the eggs from this bird have been normal. The laying ofthe soft-shelled tgg and the triple yolked egg on successive POULTRY NOTES—1909. I23 days indicates that the whole reproductive mechanism was notfunctioning in a normal, orderly and regular manner at thattime. The egg record at the time of laying of the triple yolkedegg indicates the reason of its formation. From the 24th tothe 27th inclusive the bird
