What can I use to disinfect poultry belongings? Sulphuric acid spray is good, but you will need to be very careful that you do not get it on the hands or clothing. Get 16 ounces sulphuric acid (50 per cent solution), water 6 gallons. Have the water in a wooden tub or barrel and add the sulphuric acid to the water very slowly, in order not to splash it on the flesh or clothes. But mind: nothing but wooden vessels to mix it in. When made according to directions, and of this strength it is a very valuable disinfectant, but is dangerous to use of any stronger mixing. After mixing, it can be stored in glass bottles or earthenware jugs. Another very good disinfectant for poultry houses and runs is the formaldehyde disinfectant. Formaldehyde 1 pint (40 per cent), water 2 gallons. This is fine for houses that you can shut up. Turn the fowls out of the building, close all windows, and spray thoroughly, then close the door and leave it do the work. Air well by opening windows and door several hours before the fowls go to roost. Cloth for Brooding Houses. Would some good grade of white cloth on a frame do as well, or would it be better than glass, for a brooder house, or would it keep out too much sun-heat? Cheesecloth, not heavy cloth, would be better than glass, so far as the sun is concerned. There would be none of the overheating during the middle of the day followed by the chilling at night which are caused by a large expanse of glass. On the other hand, there should not be openings on opposite sides of the house to create a draft. Also, the rat and vermin question must be considered. It might be necessary to have wire screens made to fit firmly over the cloth at night. Grains for Chickens. What variety of grain adopted for poultry food will be the best to grow, with and also without irrigation? Wheat is a standard grain for poultry feeding, and Egyptian corn is also largely used. Indian corn is also satisfactory, under the general roles for compounding poultry rations which are laid down by all authorities on the subject. Egyptian corn is very successful in the interior parts of the State, and, on lands which are winter-plowed and harrow to retain moisture, very satisfactory results can be secured by summer growth without irrigation from planting as soon as frost danger is over. Plucking Ducks and Geese. I would like to know about how, when and how often to pick old ducks so as to get the feathers for pillows and not kill the ducks, either. Will they lay any eggs while growing new feathers?
