THIN EGG SHELLS
(san diego, california)
My 2 year old Rhode Island Red chicken is not laying regularly anymore, has paper thin eggs that break when she nests, has lost feathers on the front of her neck that are not coming back. She is in a large dog run with coop inside it, not open range. "Paste" I think its called, is starting to collect in her hind area. Can you help diagnose? I live in San Diego.
