Clare’s comment: I can’t believe how my birds took to this; I am used to them ignoring their grit, but they went mad for Gastric-Grit. They have plateaued out a bit now, but still eat more of this than regular grit, I give it on alternate days. The 5kg pack is great value too.
Here's a lovely review: "Julia Leech-Howlett: This is the only grit my girls have ever actually eaten. Fabulous stuff. Since I’ve given them this my serial egg-eater has stopped smashing and eating her eggs, too! Plus her eggs are much smoother and stronger (she’s getting on a bit so they are sometimes fairly odd!). Highly recommend".
