your site helped us a great deal as we were given our first orphan calf. in the beginning, she was too weak to suck. with the info from your site, we finally got her sucking after trying for 2 days. now its been 2 weeks and shes doing great except the milk replacer has made her bowel movements very runny. is this normal? she does not appear to be sick, just very runny. can i add something to the replacer? any suggestions would be much appreciated. thanks.
