It sounds like you deal in a lot bigger quantities of birds than I do. Culling every bird on the place isn't an option for me because I keep them for different reasons than you do. I can't even imagine the feed bill with 200 birds,
It isn't bad if you use a feed mill and run them on pasture. Counting my turkeys, I'm feeding a little over 120 pounds of feed a day.
But I should clarify. I have over 200 birds at the moment, but a lot of those are meat birds. That number will be significantly downsized in the coming weeks.I won't have that many layers until my future pullets reach the right age. The goal is 400 layers eventually. Might be biting off more than I can chew, but that is the goal.
And when I say cull, I mean get rid of, either by selling the promising ones, processing some that are past laying years but still healthy, or... well culling them if they aren't suitable for either of the above.
