I didn't know that, thanks.  My girls are about 10 months old, so they still have a way to go.
 
I am focussing on fixing the runny poop issue right now, thinking that maybe this will fix the non laying as well.  So they have receive yogurt for the past 4 days now.  The poop looks better (if there is such a thing).
 
It is my first time and I am not very good at patience or consistency.  So maybe it is a combination of different feeding patterns (depending on what I was told by different people) and different space allotment.  I also have a lot of wild birds visiting, nesting and raising youngs.
 
I used to have a beautiful garden with lots of ground cover (go ahead laugh). I just imagined they would daintily scamper around and nibble (done laughing yet?). So as a knee jerk reaction, I banished them from my now former beautiful garden, to only two sides of the house. Which is enough but nearly not  as much as they used to have.
 
Then, since they were pacing in front of the gate with sad eyes, I let them in again. I am now growing dirt and rocks ... the hens have won. They are just too cute, what can I say.
 
All that to say, is had been a learning experience for all of us. So maybe, not laying is the least I can expect. I think I read somewhere that hens need a consistent routine. If it is correct, mine are ready for the shrink !
