Perhaps breeding hedgies obtained from pet shops isnt a good idea but i just wanted to point out that any hedgie with lineage or not are suseptible to an array of health problems and lineage is no guarantee to health.
Health issues can occur in both lined and unlined at any time.I speak from personal expirience of course.
Having hedgies with lineage though is of course a major advantage as any conditions in those lines are noted and are obtainable if the breeder reports such a condition.But it's not really applicable to various conditions which are not hereditary.
I myself have females with limited lines but i do know the breeders and where parents and grandparents ect have originated something which of course you cannot possibly know when obtaining from pet shops...so a very wise decision you made indeed.
Beautiful hedgies you have too by the way.
