The first thing I'd do would be to take that baby's temperature. If she has a temp, and I hope she doesn't, you might want to consider getting a vet involved. With her muscle weakness I'd go ahead and give her a bit of selenium. You can get a Selenium and Vit E gel from most farm/feed supply...
You remind me of my son. Barely got that boy through high school. He hated math and refused to do it. Now he's an electrician and a site supervisor with crews at 5 different plant locations. He does computations in his head. Scary smart - and you sound just like him!
I'm sorry this is happening to your little guy.
When you say "lame" can you give us an idea of what he's able - or not able to do. Can he use them at all? Can he stand but just not walk, or not get up on his own? Pictures maybe?
@Mini Horses - Yee Haw! Baby time, lol. Two more kids made their appearance here yesterday. Buck/doe twins out of my old buck that passed a few weeks ago. Up to 8 live kids now - 3 doelings, 5 bucklings...ugh.
Ditto! DH asks me if I have my phone with me every time I go out the door.
I know shooting sounds horrific. Done correctly it's merciful, instant and painless. No watching the animal stagger around in terror. It's never an easy choice.
Like @Mini Horses said - hopefully he will lay down and pass quietly.
I'm so sorry you and Mister are going through this. :hugs
