It doesn't work immediately, give the dose and in a day or two you should see improvement. Are they able to get to mom for nursing?
I had a single buckling born this fall with his front legs bent at the "ankle". It took a couple of days for him to straighten out. And, it's painful to watch. But, he came out of it in a couple of days (I gave a dose of Bo-Se). You would not be able to pick that kid out of a group...he's totally perfect now.
Try to stay with 1 thread...it's sometimes difficult for us to determine if these are the same kids...we don't want to be giving duplicate information.
