yup.. test hatches are the only way to know for sureI do test hatches because I want to know how each cross is going to look.
way back in the stone age we used to breed dobermans. I had a nice bloodline going and had an exceptional red female . A friend of my husbands had a nice looking red male and wanted a puppy from him (he had champion bloodlines as well).. So we gave it a go.
ugliest puppies ever
I let him have two pups out of the litter as we had agreed and sold the rest with a spay neuter contract
when the owner of the stud found out he was beyond mad.. i had called his dogs puppies inferior.. how dare me!
So I laid it out for him.. even though his dog had excellent breeding and so did mine.. their genes weren't compatible for producing great dogs when bred together.. therefore as a breeder I didn't want that particular litter of puppies to go on to reproduce. They were fine as pets..but not a single one was worthy of passing on it's genes to the next generation
By doing a test breeding is the only way you will know what the offspring will really look like... luckily it's far easier to cull chickens than it is to cull a healthy .. but ugly puppy
