1, we should consider avoiding close relatives. Some ostrich farms are small in scope or large in scope, but there are not many ostriches with good consumption performance, and most of the hatched ostrich seedlings are close relatives. If you buy such chicks, their inbreeding coefficient is very high, which will cause serious degradation. We can consider buying ostrich seedlings from two farms, and mating between male and female ostriches can effectively prevent inbreeding.

2. Carefully check the pedigree of ostrich seedlings, and compare the laying performance of female ostriches with the growth curve of ostrich seedlings, whether it can fit the growth law. Look carefully at the ostrich seedlings to see if they can develop normally, especially the legs and toes, without deformation and defects. It is also important to note that the same batch of ostrich seedlings cannot be mixed with old, slow-growing stiff ostriches. Stiff ostriches usually have big heads, big toes, insensitive movements and dull feathers. It is easy to identify them by careful inspection.

3. Sex ratio of ostrich seedlings, because the purchased ostrich seedlings are used to expand the population and prepare for planting birds. The male-female ratio of breeding ostriches is 1 ratio 2 or 1 ratio 3, so you can't buy ostrich seedlings according to the male-female ratio of 1 ratio, otherwise 1 of four ostrich seedlings will be regarded as commercial ostriches, and the price of commercial ostriches is much lower than that of breeding ostriches, so you can buy ostriches. Otherwise, a synchronization will cause certain economic losses.

4. The selected male and female ostriches cannot be of the same age. Because the sexual maturity of female ostrich is half a year earlier than that of male ostrich to 1 year. Therefore, choosing the same batch of ostrich seedlings for mating will lead to no fertilization for at least half a year after laying eggs, which will cause great losses. Generally speaking, males are at least 6- 10 months older than females.

5. Age of ostrich seedlings. Ostrich seedlings grow to more than 4 months old, and their digestive function is gradually improved to adapt to various climatic conditions. Therefore, it is best to buy ostrich seedlings over 4-6 months old.
