Figure 24.—Hematoma or blood tumors of an ovary (of a hen), natural size; 
a. shows diseased ova. Note the shrunken atrophied condition; b, the sectioned 
surfaces of two of the tumors showing the coagulated blood. 
BROKEN EGGS in the oviduct, as well as injury to those ova still un¬ 
delivered, are often found and are the results of the hen being kicked or 
stepped upon by large animals. Death usually follows. We have also studied 
cases of ruptured ova due to heavy hens roosting on high perches and jumping 
upon the hard floor. 
PROLAPSE OF THE CLOACA may occur in heavy laying hens that roost 
on high perches and fly a long distance to the ground, and especially when 
the wings are clipped. If these birds are allowed low roosts, and are put on 
a light diet, recovery takes place. 
CLOACITIS.—The writer has observed one case in a cock in which there 
was inflammation of the cloaca with ulceration. The bird died later of inflam¬ 
mation extending the whole length of the rectum, infection having been pro¬ 
gressive.
