If using wire floors, take care to avoid drafts and to ensure that the birds' legs do not become stuck in the wire. Half-inch wire probably is sufficient. Young ostriches and possibly rhea will eat almost anything, especially litter, which can block the intestines, usually resulting in death. The problem may be reduced if chicks are placed on litter immediately after hatching instead of several days later. Work at Oregon State University suggests that emu chicks perform well on wood shavings as litter or on chopped grass straw.
Absorbent litter reduces labor by decreasing the time required to clean pens.
Solid surfaces, such as concrete overlaid with rubber mats, are becoming increasingly popular. Packed dirt or sand that is free of foreign material such as stones, wire, string, nails, etc. seems to be adequate. However, hard floors are difficult to clean, and as the birds age, pen floors become heavily soiled and virtually uncleanable. Top Ostrich Growing After about 1-2 months, ratites usually are grown in outside pens or pastures. At this age, they usually can tolerate normal weather conditions.
