5 Ways This Premium Grub Beats Mealworms For Healthier Molting

(Most Owners Miss #4)

Make the switch from mealworms to GrubTerra’s black soldier fly larvae for a healthier flock and a shorter molting season.

Here’s why BSFL are the ultimate upgrade:

Decrease Molting Times!

Mealworms simply don’t provide the nutrients chickens need to quickly regrow feathers. GrubTerra black soldier fly larvae are a game-changer, reducing molting times by delivering higher protein levels and 75 times more calcium than mealworms. Switch now for a shorter, smoother molting season!

Rich in proteins and minerals

Perfect Calcium to Phosphorus balance

Speeds Up Feather Regrowth

Mealworms may provide some protein, but it’s not enough for the demanding regrowth during molting. GrubTerra’s black soldier fly larvae offer superior protein content that accelerates feather regeneration, ensuring your flock bounces back faster—even if they’re not free-ranging.

TRUSTED BY CHICKEN AND BIRD-OWNERS, LOVED BY POULTRY!

I've been feeding my hens GrubTerra's black soldier fly larvae for a few months now and have seen amazing results! I have 9 hens, and before we started using GrubTerra, we were only getting about 1 egg a day. After just one month, we were up to 4-5 eggs a day! GrubTerra is an absolute must if you have chickens.
