How early is to early to start working with a calf? We have a bull calf that my daughter may show, he is not very old but came out the door pushing 100 lbs. and is growing like a weed. The first few days you could walk right up to him and pet all over him. He does not seem to be wild, but after the week in the pasture with the other calves he no longer feels like being cuddled. I have not tried to halter him yet, but I feel like once he is haltered he will likely not be to much of a problem but I could be fooled. I didn't know if anyone has had problems with starting to early, whether it be by injuring the calf or having negative reactions from starting at to young of an age.
