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?
