Ive never before gotten a calf from the sale barn but we picked one up 1 week ago today for my son. We picked it up just hours after it was born. We have kept it isolated from anyother calves that we have in our corrals(we have a set of twins and their momma back there)to be sure it didnt come down with anything. So far she appears healthy, ddrinks her bottles well and has normal poop for her age. My question- When can I safely turn her out in the corrals with the twin calves? I dont want to pass any virus along to the twins. The bum calf loves to be outside running around!! Thanks for all your help!
