Actually, I saw your info about the ziplock bags and hand pump in a post a few days ago and ordered them off Amazon. They should arrive tomorrow. I thought I would resize into the smaller bags, then put those into other bags. I'm trying to protect my investment, the nutritional value and the "Yumminess" of the mice.
Layne Labs' shipping was $87 on a 350 varied-size mouse order of $189. That's .79 per feeder and well worth it if I can keep them properly frozen. No bedding, fecal matter or frozen urine.
For comparison: American Rodent Supply shipping was $29 on a 200 varied-size mouse order of $89. That's $.59 per feeder, and a total that's much easier to see. Except for the jumbos, which I think were a tad old, the rest were well received by everyone. But there was a very small amount of bedding,fecal matter and frozen urine in with the mice and a few were quite intertwined.
...and now I'm going to sound stupid...but the LL rodents look more peaceful all straight and tail- tucked, than the ARS rodents where some are splayed out or a bit twisted around. :shrugs:
