Any last minute suggestions? I have to run to the store and get more starter (i had a bag last week, but due to an unfotunate water accident it's all ruined..thanks kids!! ) and i have the bag ofdry cat food to grind up for them if need be. How fine do i need to grind the feed and cat food to start with? I am so stinkin excited!! Wish my chickies safe travels! And i will update when they come to my post office and to my home.
