Using kennels as reclaim should be completely out of the question from the start since they dont move with the unit while reclaiming, so unless you have an hour of time you aint reclaiming a gc thats being microed.
Hives work way easier for this since they have way more range so you cant just walk a t4 or some randon t3 units in a hive farm range, although you should realise that walking units into range of a 20k mass shielded bp farm is probably not the best idea
