Are you going to re-home him or? If it is re-homing, at 10 I would consider involving her in that process so that she can feel some ownership in securing his next home and knowing that even though he can't stay with you guys she is helping to be responsible for finding him someplace he will be okay (this, though, would require being sure the intended home is not going to tell her they are going to eat him, etc - less likely with a bantam, but still a possibility). I find that making kids part of the process can help them process it all better.
