We have a rir we adopted. Don't know her age. Was told she was young, but was laying big beautiful eggs when we got her. One every day. Got her in October. She stopped laying about 2 weeks ago. Was doing fine then this morning found her with an egg, but was extremely lethargic and eyes closed and went get up. Egg looked perfectly formed. I broke it for her and force feed her a little and gave her yogurt. She's cold and not moving. HELP!
