please help! got 2 chickens -4 months old in July-an Americauna and Rhode Island Red -both started laying in September. So far, 19 eggs have been laid with 7 having been eaten - by the Rhode Island Red. Not sure what to do - would prefer not to cull her. Any suggestions? have tried golf balls, wooden eggs, plenty of oyster shell and let them out for about an hour a day to roam.
