on which they are due to be hatched, and left totally un- 

 protected for a period of six hours in warm weather, and 

 even a much longer time, and if again replaced under the 

 hen, they will be hatched, and the chicks survive. I have 

 likewise found that eggs which have been sat upon for a 

 period of two days may be removed for a corresponding 

 period, and afterwards returned to the nest without injury 

 to them; but, as a matter of course, they must be sat upon 

 the full time i.e., thirteen days before they will hatch. 

 These facts are worth knowing, and it would be well if fanciers 

 would make sacrifices by way of experiment occasionally, and 

 give the results of their labours for the edification and en- 

 lightenment of their brother fanciers. Eggs have been known 

 to be hatched that have been kept for a period of eight days 

 before being set, and it is quite possible that eggs kept even 

 for a period of twelve days might prove fruitful.
