Today I noticed my 2 year old female Nigerian Dwarf trying to mount her 1 year old daughter. I didn't pay much attention thinking they're just playing around or trying to establish dominace but as soon as she "finished" I noticed a significant amount of white discharge dripping from the momma. Is this normal? should I be worried? I do not have a Nigerian Dwarf male with this herd so they will not be bred this year. Does anyone have any advice on this?
