The eggs laid by Brahman chickens are preserved in the same way as domestic chickens, so we must pay attention to temperature control when preserving them. The incubation period of Brahman eggs is generally 2 1 day. Chickens are physically weak and have poor feeding ability. When raising chickens, we must ensure the surrounding temperature, and the room temperature must be above 30℃ on the first day of chicken shell breaking. With the growth of the chicken, the temperature gradually decreases, generally about 7 days, 1-2℃.
