It's funny since you mentioned it not seeming normal for the eggs to be misshapen I've really started to inspect the eggs. It's my NHR, Ginger, that has been laying the weird eggs. They are exceptionally long and a little rippled at the very top. And the last two have actually had tiny holes in the top and had to be thrown away.
I feed my girls a combo of Nutrena Layer pellets and Feather Fixer pellets. They have Oyster shell in a little rabbit feeder free choice. I also string up "Hot Cakes" once a week for them to peck at. They also get lots of spinach from my garden, strawberries, blueberries, raw corn on the cob, other veggie and fruit scraps and sometimes they get leftover fish like salmon or steelhead trout. I keep their hen house super clean with fresh pine shaving bedding in the nesting boxes and fresh rosemary clippings throughout the hen house. I put DE powder in their dust bath spots once a month.
I feel like they are pretty pampered but I like it that way since I'm eating food from their body. Any ideas of what could be causing these weird eggs? My hens are now 1 year and 3 months old. My NHR have laid more eggs than any of the other breeds.
