Glad to hear things are moving at least a little bit. And I wouldn't worry too much about the spilled feed. Like you noted when you asked others to make sure the wildlife had water, there are plenty of wild birds that are struggling to find enough food in a burned out, ash-covered landscape. You just helped some songbirds survive ... or at least a few pigeons!
Once Henry and the girls get home, they can join Turtle in their own version of mini quarantine. If it makes you feel better, dose them with some preventive meds, maybe some wormer and a course of antibiotics, if you can lay your hands on any. My guess is that they'll be fine, though. I'm sure their foster mother would not have volunteered to harbor them if she suspected she had any issues to share. Your biggest issue is likely going to be simply the stress of moving around ... which you couldn't possibly sympathize with, right? (I know .. smack me now and I'll act contrite for a bit ...)
And if Henry likes horses, maybe there's a mini out there that needs a home, now ... (smack me, again?) I know someone found a burro standing in the middle of Branstetter ... just sayin' y'know?
I think I'll sign off now, before I get myself into trouble I can't talk my way out of ... good thing I'm all the way out on the East Coast ...
Stay safe - and know that there are prayers coming your way every day.
Oh - and the next time you see him, tell Henry that Herman says "Hello!"
