Interior oF MuLtTipLeE Unit House. 
This is one of our houses, The drinking fountains stand in the passageway and their fronts 
project through the wire netting under the first row of nest boxes. The nest boxes are empty 
ege crates and do not open at the back. The feed troughs are inside of each pen. In other 
houses, we set the feed troughs alongside the drinkers in the alleyway and cut away the netting so 
the birds can feed from them. We like the last arrang it best b the troughs can be filled 
quicker from the passageway, and the time of opening and closing doors and going into pens is 
saved.
