Sooner I am sorry to hear about your loss I am having the same problem with my silkies the only difference is that they seeem to be killing there selves they are still young and shouldnt be overcrowded but they always seem to huddle in the corner why I dont know but that is what they are doing still got a lamp on them at night to make sure that they arent getting to cold but doesnt seem to help!!! But anyhow if I have any silkies left come poops time I will be bringing a load with me!
