I originally picked a Rouen and a runner mix up from the feed store and went back for 2 KC's I spotted. One of the KC's I chose because she was smallest (hoping for a female ) unfortunately she just likes eating weird stuff. The runner and the smaller KC' are not eating as well, not growing as quickly, and their crops are significantly harder than the other two, full and/or empty. They were on pine shavings until I caught the small KC choking on a piece. They are now on pee pads until they learn to eat their feed. How do I clear the impaction? How long can they go without feed? I'm afraid to take it overnight with them being so young? I've been massaging but it's only been a day and I'm paranoid! They're eating, drinking and running I just want to head thugs off before it they start getting sick.
