Purina Flock Raiser + Oyster Shell...brittle egg shells

[vantain]

I have a mixed flock and use Raiser + oyster shell. I’ve also noticed weaker shells lately. I also started mixing layer feed with the Raiser and that solved the problem. I’m mixing 1/2 to 1/2.

Yep..that's what I did too. It's helped.

I started doing the same..just mixing in some of the layer feed. Unfortunately, the layer feed is pellets, and the flock raiser is crumbles..and you know chickens..lots of pellets on the floor of the run near the feeder! Silly chickens.

You should be able to find a layer crumble for your mix.
