Thanks everyone.
I'm going to check out what I can find locally. I only have 2 clutches so I'm just going to scrap something together for this season. Next year I'll probably just buy a professional rack. I do like the v-18s though for sure. the extra length seems like it prolongs the life a lot. I think that's almost the floor space or bigger than a 15 qt, but the narrow design and low height gives more security to a little baby.
Somewhat jumping topics, and I can make another thread if needed... Deborah I think? mentioned a short list at some point of things every breeder should have on hand for emergency treating as the babies hatch. The one item I remember is dental floss for tying cords if needed. What else is on that list and what would it be needed for?
