Laying Blocks: MORTAR FOR block-laying consists of cement and fine sand mixed together with water to form a self-hardening paste. Mortar mixed in the proportions one part cement to five parts sand is adequate for laying blocks. It is vital to mix the ingredients in the correct proportion. Use buckets as a measure for the ingredients, tipping them on a hard, flat surface or a mixing board.
A large percentage of new housing for laying hens makes use of laying cages in which hens are housed one to three per cage. Several tiers of cages may be used to make the best use of the space inside the laying house. Feed and water are supplied by automatic systems, and automatic egg-gathering equipment brings the eggs to a central location for processing and packaging. With such systems, one man may take care of up to 25,000 laying hens. Many very large egg-producing units with as many as several hundred thousand laying hens are now in existence.
