Analysis of Ovulation-Oviposition Patterns in the Domestic Fowl by Telemetry Measurement of Deep Body Temperature

Continuous temperature records in relation to time of oviposition and behaviour associated with it are summarized for 13 laying strain pullets with a regular pattern of oviposition and for a further 10 pullets which were either 'internal layers' , or natural or induced layers of membranous-shell eggs. The records of five pullets, in which the most recently ruptured follicle was excised within 2-5 h after ovulation, and of four control pullets are also included.
