Depth should always be a concern. We have to maintain a flock that is deep enough. We have to hatch enough to maintain that depth.
Selecting vigorous individuals is the number one priority. Even with seemingly appropriate depth, selection can ruin them alone. Health and vigor is priority number one. It is impossible to understate this. If some of our best males is not also some of our mot vigorous males, then we are not hatching enough.
There is variability in the qty. that we hatch. That variability is our genetic depth. Some of this is seen, and some of it is hidden.
This point has been debated here, but it was never understood. This genetic depth is insurance. We try to preserve our efforts. A necessary outcross is added risk.
Many cannot hatch hundreds etc. If they can only hatch 40, then hatching a family at a time is possible. One in the spring, another in the fall, another the next spring etc. There are many possibilities, but not maintaining depth is not one of the possibilities.
The side mating contributes to depth. I believe in them for a number of reasons.
How many is deep enough? That could be debated from here until the end of time. 4 cocks and 16 hens may be deep enough. 3 cocks, and 24 hens may be deep enough. These are minimums. How many families? Two at least, maybe 3, 4, or even 5. This is to maintain a single strain. Multiple strains require multiple similar efforts.
A utility flock needs to be vigorous. Bringing in new birds through side mating is inevitable. When it becomes absolutely necessary, then caution is the rule. It will take a generation or two to even get it added in. Looking ahead is important.
If the above numbers sound unrealistic, bantams are an option. They really are. Some are good layers, and they grow fast.
Poultry tolerates a remarkable amount of inbreeding. It takes an awful lot of inbreeding to see any abnormalities creep in. Egg laying, poor gains etc. is what we see go first. Someone that knows their birds can see it long before physical abnormalities creep in. It is an awfully mall flock that is already inbred that will see any problems in the near future.
