Well once I have established proper type on a project, then it's time to buckle down and fine tune the pattern/color.
Try to only use the cleanest laced birds in your breeding pens But if a bird js just so superior in type/size, it will probably be worth delaying the clean lacing a little longer. It's a process
The is a old breeder saying that goes. "You will get what you will tolerate" Which I take to mean, if you use birds in your breeding pen that have faults, don't be surprised if the resulting chicks also carry those faults.
A breeder is usually way ahead raising less chicks using fewer numbers of the best birds they may have in their breeding pens, instead of including any marginal birds. This is what often differentiates a breeder from those producing eggs/chicks/birds for sale, where numbers tend to trump quality.
