I think these three boys will be fed for awhile until I can see more of how they fill in/out, temperament etc... this is my first attempt at breeding so culling will be a loooooong process until I feel confident.
Yep...when you are trying to do everything right and comparing between different birds in the grow out group feels like splitting hair the decision is really hard. Some years after I choose the keeper they look 100 times better knowing that for better or worse they are who I am going to be working with for the next year. When that happens I know I have made the right choice. Other times I have the buyer remorse and want to go back and undo things. Those years are not the end of the world. I keep 50% of the breeding flock (the best ones) and rotate out the other 50% (the ones that I had buyers remorse with) each year to make room for the currents year's grow out group. So if the new group isn't great I still have my best stock to work with the following year aa well as being able to test drive the new generation for a year to see what they are made of before culling down to the best 50% of all the flock for the next year. As long as you are learning as you go your flock will improve. Some birds may only stay in the breeding flock one year others may be their for 5 or more years. I never cull older birds unless younger birds are better than the older ones. The older ones tend to stay for a long time so I don't have to know everything about them at 6 months old. I can watch them through multiple years and watch their offspring etc.
