Abstract
1. Eggs from an egg-type breeding flock were collected at 08.00, 11.00 , 14.00 and 17.00 h each day. 2. Eggs laid between 05.00 and 11.00 h h ad higher fertility than eggs laid between 11.00 and 17.00 h. 3. Hatch ability of fertile eggs was highest in eggs laid between 05.00 and 08. 00 h. Hatchability decreased progressively for eggs laid later in the day. 4. It may be more economic to use eggs laid from 14.00 to 17.00 h as table eggs rather than hatching eggs.
