Hmm i'll have to check out Layne Labs. I just buy live from my reptile shop and then bring them home all the food and kill it all myself and feed everyone. I'd just use them for birds as the last time I asked about live chicks, I made the mistake of mentioning I was feeding them to snakes and omg you could feel the heat of the burning rage from the store people. Morale, don't ever say you are going to feed baby birds to anything, they will always be pets!!
