The worst part about feeding 6 greyhounds raw food is that you need a lot of chicken backs. I remember the day when I only had 2 greyhounds and a box or 2 of chicken backs lasted a month. Yesterday, we purchased our 2 1/2 month supply of chicken backs = 360 pounds. I know it sounds like a lot........ and your right, it is :-). It takes us almost 2 hours to place them all into containers and into our 2 upright freezers. I'd much rather process a large volume at one time and have it last for a few months. Otherwise, I'd be purchasing chicken backs every week. Once we have our large supply in place, feeding raw food is easy, but I will admit that this part is more time consuming than just buying a bag of kibble.... and while they are starting to make raw food that comes in a bag..... I'm not quite willing to pay the hefty price....... especially for 6 greyhounds.
