Thanks collie for the info. We have 38 first calve heifers this year our birth date stared on January 24 so far we have only had help one out. The heifers are all close in when they get springy we bring them to the barn so we can watch them and help if needed and give them extra feed after about 2 weeks they get turned out with cows to roam the ranch. Right now because of the drought we are feeding all the cows everyday. We have been feeding since we brought them home from there summer range there never has been any grass this year because of the drought we are lucky we grow all of our own hay.
