Hoping to pick some brains on this one. Our girls (and one roo) are at the 23 week mark. Two girls are laying steadily, one is laying soft shelled eggs with the occasional "good"egg, two more are squatting nicely, and the last gal barely has a red face. No squatting or anything like that from my late blooming hen, she still doesn't have a clue. My question is this: I've got them on laying feed, and they get to free range supervised in the backyard, but after a week of the soft shelled eggs, perhaps I should go ahead and start adding the Oyster shell. I've been waiting to make the Oyster shell available because of potential harm to my late bloomer, but I wonder if the other girls--especially the soft shell gal--might need it. What would you do? Thanks in advance!
