We had this unusual egg shell today, with purplish raised dots...is this a sign of something lacking in diet or too much calcium? Any ideas? Thanks!
We have a couple of our Black Stars that lay eggs with raised purple bits, it isn't every time and some eggs have more than others. I will be interested to see what some of the more experienced on BYC have to say.
The system gets "clogged" every now and then. Calcium applicator gets clunky and the spray booth jets sometimes don't spray on the brown paint evenly. Did you call maintenance?
1. Inherited 2. Excessive use of antibiotics 3. Excess calcium consumption by the hens 4. Copper deficiency 5. Incorrect or changes in lighting program 6. Water shortages 7. Imbalance in Calcium carbonate, Phosphorus, Magnesium 8. Stress Chris
Chris09: We have no way to know if this is inherited. We purchased, rescued, these hens at age 17 months, in August. We have not used any antibiotics, and neither did the previous owner. We are feeding Nutrena layer pellets with free choice oyster/egg shell. How would we determine a copper deficiency? We have not and are not supplementing light. We have three waterers for 30 layers, two 3 gallon and one 1 gallon, all changed and filled daily. How would we determine Calcium carbonate, phosphorus, magnesium imbalance? Stress - always possible as we are learning that any small change in daily routine, weather, several are just recovering from moulting. We get one to two eggs a month that have the raised bits, if deficiencies or imbalances were present wouldn't the bits be present on every egg, or at least more often? Fred's Hens: Love the mental picture of the clogged spray booth jets. Around our place DH is maintenance, and he says he's going to have to find a "Clogged Spray Booth Jets for Dummies". Anyone seen that title?
