Calves, kids, and lambs must have reached an adequate physical size before they start wearing collars. The animal must have an adequate size and build to carry a collar without it interfering with its natural behaviour.
There are large variations between species, breeds, and individuals. Nofence has no basis for giving exact advice about when animals are big or mature enough to start wearing a collar.
It is important that the size and weight of the collar do not limit the animal’s behaviour.
When using Nofence on small animals, it is extra important to check that the chain is in contact with the animal’s neck. If the neck is too small in relation to the length of the neck strap, the contact points will come too far down, and the animal may not feel the electric pulse. Efficient delivery of the electric pulse ensures that the animals learn how the system works, and to respect the Nofence boundary.
