I have bought a bag of mixed lettuce for Shelby i fed these every other day and use different combos. This new bag as Red Chard in it i was not sure it was safe but as its got 3 other leafs in it i know are safe to feed i got it, and said i would take it out if its bad. I have done a check and its come up with Spinichand cabbage, and the Tort trust are saying not to fed it as it binds calcium, but i thought i would double check with u guys as some sites are saying Red Chard is safe. There is way to much conflicting advice out there its really confusing for new Tort owners like me!
