I will probably do this this winter, free feed both corn and gamebird pellets which have a very high protein content. If you are going to "string it along" you need to make sure that at least the protein needs are still being met! The high carbs of the corn to help stay warm, keep weight on Our corn is up to $11 a 50#, and gamebird pellets here are $15 a bag, Prince brand? My birds like it and it's actually cheaper than "flock raiser" in the same brand which has lower protein? Idk why. I also offer calcium free choice (oyster shell)or do you mix your own grains in to string it along?
