My pekin girl, Yuki, who is still recovering from her broken leg, laid a soft- shelled egg in the duck pool last night or this morning.. or at least I think it was her. She has laid two eggs in the time we've had her.. maybe a month or so? Her first one she laid a while ago and she laid it in a puddle I also just learned that spinach can make duck's eggs go soft or shell-less (thanks Nettie!) and I feed my chickens and ducks spinach all of the time. We are going to start feeding the ducks dog food more often, get more oyster shells, and feed them yogurt and cottage cheese. I guess my reason for posting this is for advice.. or experience? Could the pool have made the egg soft if it sat in it long enough? It was just the membrane, no hard shell. Thanks in advance!
