Quote: THe grains occurred when I gave the girls free access to oyster shell in addition to a layer with 3.25% calcium. My marans are not every day layers so the calcium demand to build a shell is not the same as another that lays everyday. I removed the oyster shell and all went back to normal.
In nature I don't know if a rooster would eat the same as a pullet/hen. WOuld be an interesting to observe choices. Certainly the rooster eats much less feed overall compared to a laying hen. If a rooster is free ranged all daylong-- doesn'the get vit D from the sun too? That would be in additin to the feed content of D. I"m not sure that the feed that is commerically available for the alyers takes the boys into account. DO most backyard flocks have roosters?? I don't know the answer to that.
I am reconsidering the mix of feed I have as the roosters I have now I would like to last a few more years. Meaning I am considering changing their mix to a 22% protein turkey feed and mixing it with whole corn and oats. ANd a little oyster shell on the side.
