<p>The present invention relates to an improved hatcher structure which is more efficient than conventional hatchers and which is easier to construct, operate and service. In particular, the hatcher of the present invention utilizes a restricted area, high pressure zone of air to control the exhaust of air from within the chamber and, in turn, control the intake of cooler external air into the chamber and the mixing of that air with the internal air. To achieve this control, the hatcher of the present invention further utilizes a mobile environmental adjustment system and an alignment mechanism which ensures precise and consistent placement of the environmental adjustment system within the chamber. In addition, the present invention employs an improved frame post and doorway seal which facilitate construction, operation and maintenance and which promote internal environmental consistency.</p> |
