I get mine from Rona lol I bought a 7 doller bag 3 years ago and just ran out this season time to get more lol if I never seen this I wouldn't have noticed
I also use just the vermiculite while incubating and never had any problems and all my eggs have had a 100% hatch rate unless they were slugs but fingers crossed I never get any but I have had 0 slugs in my 5 clutches so far and I've even hatched an egg that was 2 that formed together in the mom I thought it was a funny egg at first but then seen the line that made it 2 separate eggs both albinos
