Hi, sorry to hear about your silkie. I see you've already posted on the ER form and @janiedoe has given some good advice here on this thread, so best wishes, hope all that helps.
I raise/breed silkies, and I too have had adolescents shipped in, so my heart goes out to you. I did post on your ER post what I do for ours that are ailing. I hope she pulls through this.
