INCUBATION Q7 
moved, a burlap frame placed in the bottom 
of the nursery, and the chicks removed by 
hand from the egg tray to the nursery. 
They should not be allowed to drop down to 
the nursery floor, because the change in tem- 
perature is too great, especially if the chicks 
are not hardened off, and the fall may 
be injurious. After the chicks have been 
transferred to the nursery the egg tray should 
be taken out, thoroughly washed with some 
good disinfectant, and placed in the sun to 
dry. Any ventilators on the machine 
should be opened wide and the door should 
be fastened so that there will be an opening 
an inch wide at the top. The chicks should 
then be kept in the nursery, given no feed 
nor water for at least thirty-six hours, to 
thoroughly harden them off and get them 
ready for transfer to the brooder.
