Thank you all. I figured it was normal but wanted to be absolutely sure. I have them on a high quality organic layer feed and have been giving oyster shell since 18 weeks. I'll stay the course!
I got my first egg on Saturday from my flock of six Buff Orpingtons (approx 20 weeks old). Nice egg, good strong shell. The next day I found two "rubber" eggs-- but since then, nothing. I know it has only been a few days but is it common for a hen to lay one good egg to start and then nothing at...
