I have 3 chicks that were born in April. One was injured about the time the other 2 started laying, but she has never laid an egg. She had a head injury, but after about 6 weeks of me hand feeding her and some water therapy, she is 98% normal. For her, I doubt if she will ever lay an egg, but for the other 2, they stopped laying when I introduced the injured chicken back to the coop. Either that or they're eating the eggs, but I'm not seeing any evidence that is happening. The healthy girls were laying daily for several weeks, so I'm really confused as to what may have happened. It's been over 2 weeks since Skittles rejoined the flock, so I would think if it was shock at her return (though they all had free range time together for 2 or 3 weeks before I put her back in) that they should be back to normal now. Anyone have any ideas?
