I am feeling pretty confused right now. We are fairly new to the chicken game and just starting to get the hang of things. Below are our chickens and what I know about them. All were purchased from someone nearby with what seems to be healthy, if not slightly overcrowded birds, probably not super high quality genetics, which isn't that important to me because I won't be doing any breeding. I'm going by the breed names that the seller gave me. Their appearance seems consistent with my research on the various breeds. We got a couple of the birds 3 weeks ago, and 3 more just a few days ago. I wasn't expecting to see "new" eggs in the nest box for a while, so this was quite the surprise.
Ameraucana mix - 16 months old - For the last 2 weeks we have been getting 5 eggs a week. They are a pale grey-green color, usually very consistent, sometimes half will be more brown than the other half of the egg. Solid shells.
Red Sex Link - 16 months old - For the last week, we have been having some egg "issues." She's been laying exclusively in/from the roost at night. This has resulted in 2 eggs with shells - one was VERY soft, the other got a ding in the shell when it landed on the roost (and magically didn't roll off). There have been at least 1, but I suspect 2 shell-less eggs that I believe were at least partially consumed - no other egg eating behavior has been displayed. The 2 eggs that have had shells have just been a standard light brown. No eggs she's laid have been anywhere near the nest box.
Black Copper Marans - 16 months old - We got her 3 days ago. She was a favorite of one of their roosters and is needing to fill in on her back and head. Sweet as pie.
Black "Langshan" - 16 months old - We got her 3 days ago - This chicken has white streaks that are not consistent with the breed. I asked the langshan thread and at least one person believes that she may be a mutt. Her comb resembles a pea comb and langshans should be straight combed. She is who I suspect the most, but I guess that I expected that if she laid a different colored egg, it would still have that pinkish bloom that langshans are supposed to have. I'm not 100% confident that this chicken isn't a male. The seller swears up and down that she's laying eggs, and has offered to swap her out if she turns out to be male, so has nothing to gain by convincing me that she's female if she isn't.
Speckled Sussex - 4 months old - we got her 3 days ago - This is the only chicken that I'm reasonably confident is not laying. Her comb is still pretty pale and she hasn't filled in much.
