SELF-FEEDER FOR GRAIN. 
This trough gives excellent satisfaction with us. We do not sell it, but will tell you how to have 
it made, Itis four feet long. At the bottom of this page you will see a sectional view of it. The 
grain is put into the hopper, H. It drops in the direction indicated by the arrows into the spaces, AA, 
where it is eaten by the birds. As fast as they eat, more drops down. The strip through which they 
stick their heads is three inches wide and the slots are cut with a band or keyhole saw. The V at 
the bottom of the trough is made from a solid piece of four by four. It is solid so that rats cannot 
get inside of it and hide and pilfer the grain. The inch square pieces at the front of the bottom 
prevent the birds from pecking the grain out on to the floor. One-inch lumber is used in the con- 
struction for every part except the slot-boards, BB, which are three-eighths inches thick. The top 
and bottom are of twelve-inch boards, the sides of ten-inch boards. The top is held in place by a 
hook and eye at each end as pictured. The trough will hold from three days’ to two weeks’ supply 
of grain, depending on the size of the flock. Put the trough not in the flying pen, but inside the 
squab house. Or, you may build a half-trough(slot-board down one side only) and set it in the 
passageway, and it will fill the space between the lower tier of nest boxes and the floor. Here it may 
be filled from the passageway, and you will not have to enter the unit pen. We have tried all kinds 
of self-feeders and r d this pattern as the best of all. If you adopt it in connection with 
the dowel system (illustrated on previous page) your dowels will be used only behind the drinker, this 
trough taking up four feet of the rest of the space. Make it either longer or shorter than four feet, 
to suit the size of your flock, if you wish.
