Ventilation. Plenty of ventilation is required in 

 the brooder house in order to take out the ammonia 

 odor which arises from the droppings. Properly 

 managed, the doors and windows provide sufficient 

 means of ventilation but some duck growers prefer 

 to have roof ventilators in addition. 



Other Types of Brooder Houses. Many other 

 types of brooder houses are used, some of them 

 being shed roof construction and many of them 

 being built narrower than this house, that is to say, 

 14, 16 or 18 feet wide with an alleyway along the 

 front or rear side of the house from which the work 

 is done. The hovers are placed at the back of the 

 pens when the alley-way is in the front, otherwise, 

 they are placed next to the alley-way. The disad- 

 vantages of these houses are that only single pens 

 are provided and that valuable brooding space is 

 used up by the alley-way. The advantages of the 

 house described above lie in the fact that the hovers 

 are in the center of the house with the pens on each 

 side of this, thus doubling the capacity, and that by 

 making use of a walk over the hover pipe no room 

 is wasted in an alley-way. Having pens on each 

 side also lessens the labor of taking care of the 

 ducklings to some extent as the arrangement is more 

 compact.
