BUT... then I took a good look at how many there were....
I split the boys up by size. seven in one cage, six in another. Seemed an equitable split. I let them all run around together like crazy kids for a couple of hours. Getting them used to each others smells and what not so they aren't being bossy with each other in a more confined area.
Triscuits kits are overall the largest. I marked their ears with one or two lines depending on how much I like them at this age. Only marked Triscuits since I want to be able to tell them apart as they mature. She has a couple I really like the feel of. The lad was quite intrigued with me as I did this.
