The Creme d’Argent and Silver Marten hybrid kits are now a week old. You can see their agouti coloration really starting to come in. If past litters have been any indication, not only will these kits grow faster than purebreds, they will mature faster and will probably all be humping each other at ten weeks old. My purebred kits don’t get interested in that kind of stuff until at least about twelve weeks.
