Here's why:
* Maggots are the larval stage of flies. Flies are attracted to decaying organic matter, including dead animals.
* Flies lay eggs. Female flies will lay their eggs on the carcass of a dead horse.
* Eggs hatch into maggots. The eggs hatch within a few hours to a day, and the maggots begin feeding on the flesh.
This process is a natural part of decomposition and helps to break down the dead animal. It's important to note that the presence of maggots is not necessarily a sign of foul play or neglect. However, it's essential to properly dispose of dead animals to prevent the spread of disease.
