Description
Fei Zhang and colleagues published a chicken development study in 2026. They tracked the crop, a feed storage organ in poultry. The crop ferments feed with lactic acid bacteria. Its growth across the full life cycle was unclear. A slow-growing black-boned breed was studied closely. Birds were sampled from hatch to adulthood regularly. Crop structure, local immunity, and microbes were measured. Ten birds were sampled at each time point.
Early weeks built the crop structure and microbes. Muscle and lining layers thickened and stabilized gradually. A protective antibody rose steadily during this phase. Mucin-related genes switched on strongly very early. Microbes shifted toward lactic acid bacteria dominance. Later stages refined function rather than building anew. Feed efficiency and gut health link to these changes. Farmers may time feeding strategies to development.
