I have a newer female duck that is laying eggs out of sequence. She's is a pekin around a 1 1/2 yrs old and we got her close to a month ago (we got her with a male, but we had to get rid of him, we already had a male) She is laying soft shelled eggs but they stared getting a little harder, ( i still need to make a bowl for oyster shell for her). But that's not the problem. This has happened a couple times in the past several weeks. I let her out of the duck house in the morning and find an egg, not real hard but solid enough that it wasn't crushed, but then later that night before bed i find another egg, usually broken on the ground (doesn't form a hard shell). So that makes this girl laying 2 eggs with in a 24 hr period Other things going on, Once we got rid of her male she seemed fine. We have a male hatched this year but he must still be too young because he doesn't actually breed with the girls he just chases them away or bites there necks, never mounting. So i guess because our male isn't doing his job this girl is usually getting on top of the other female acting like a male. Not sure if its her hormones that is messing up her reproductive system or not, or if it was the stress of moving We also are treating her feet with bumblefoot (one foot at a time) so we change the bandage when needed, she doesn't really like to be grabbed.
