American grubs

American or white grubs are a specific kind of grubs of scarab beetles that usually damage turfgrass in several parts of America. Those grubs can be identified by the hairs or spines on their last segment of the abdomen. Most damages to those grubs do not come from themselves but from those animals who love to eat those grubs.

These grubs are a very good meal for your chickens as they are rich in several nutrients, along with 40% more protein, 27% crude fat, and even 85X more calcium than mealworms. Not only the big chickens but the baby chicken can also have American grubs.

Grubs not only add variety to the diet of your chickens but also give them the right kind of essential nutrients. Eating grubs can ensure that your chicken will have healthy feathers and bones. You just need to ensure that your chicken drinks plenty of water while having grubs as their meal.

Moreover, ensure how much American grub can your chickens have every day because moderation is important to make sure that they do not consume too much protein.

Mealworms are mainly the larvae of the insect known as the darkling beetle. These beetles feed on the leaves of the plant and young seedlings.

Those mealworms contain about 25% fat, 50% protein, 7% fiber, and even a little amount of calcium. However, similar to American grubs, you should ensure how many mealworms your chickens can consume at a time.

Moreover, you need to remember that the nutritional value of both grubs and mealworms depends on the diet requirement of the chickens.
