I have a guernsey cow bred back by jersey bull and a jersey cow bred back by same jersey bull. I cannot prove they are pregnant but I have seen them with the bull. Guernsey is still currently in milk. This will be their second calving and did fine on their own first go round. They should be due February or March. Don’t want to separate them since they have always been together. They can be hand milked and have great teet size.
