That calf may go to trying to suck other heifers and ruin their udders.
Sh!t can her and start with something that will not cause all these problems. That is the downside to raising calves on nurse cows.
I raised several and kept them and bred them... caught 2 of them that started sucking some of the other heifers AFTER they had calved... their calf is sucking them from the side and they are standing behind another fresh heifer sucking her from the back.
Used the nose flap things and they managed to get them off. Tried sucking around them too.....and yes, the cow kicked so didn't want it for their own new calf to get kicked. Shipped the one and the other went into a field with older cows totally away from her "sisters" (heifers she grew up with) and she got chased off and butted good by a couple of cows.... If I catch her ONE TIME trying to suck again... I don't care who she is, she will be gone.
When I weaned this group, (the 3 cows they had been on had all co-mothered the 8 calves) ; so they were moved away with just other calves, didn't seem to bother the other calves, and got bred and did NOT go with any other lactating animals until they freshened themselves...... The other 6 had not been a problem with sucking but 2 did not breed back and since they were the most "dairy" looking, and had not held their condition.... I shipped them. So, I have 5 of them left with their second calves on the ground. Been watching for any sucking from that one but so far, nothing. One has a sorry calf, the first was nothing special, so this will be her last go-round here.
