When to introduce oyster shell?

To be fair to the OP (Eryniel), I think that she only came back once to thank everyone politely for their help.

That is correct, Morrigan

Your rirs look like production reds

I have 4 pullets that were hatched on Thanksgiving, 2 RIR's and 2 Black Sex Links. I also have a year old roo. Recently my 2 RIR's combs started turning a deep red, and their wattles have doubled in size (but my sex links haven't changed yet). Based on this, when should I begin leaving oyster shell out? I just bought some to have ready, but I'm not sure when to start leaving it in the coop.
Below is a picture of one of my RIR's, and one of my Sex Links, for comparison.View attachment 1298411 View attachment 1298412

Agrees.
@jvls1942 has the OP confused with another member.

One brand says to offer at 18 weeks, a brand I have says to offer during laying season. In my opinion, I would offer it at 16 weeks. Of course if you have a mixed ages flock, they would have access earlier than that. GC

I apologize , it was other members..
I don't always look at who posted, I just read the posts..
anyway, chickens eat just about anything.
yogurt is dairy and just read through many post here on byc to see how many people feed yogurt..
on the farm the chickens would almost beat the cats to the pan of milk..
often our chickens were fed outdated cheese sandwiches..
they won't eat it if they don't like it..
