My Muscovy hen, Paddles, started laying on Feb the 10th. The last four eggs she's laid have been jelly eggs. She seems fine, eating, drinking, and doing her thing. She gets Layena (and sometimes the cats' food) along with free choice oyster shell. I read that a D3 deficiency can cause it but they get Rooster Booster in their drinking water year round and it has vitamin D3 in it. Our drake is a house pet so it couldn't be over-breeding. I'm stumped! Any advice is appreciated!
