Hi everyone! I have seen a wonky egg for the past 2 days (see attached of one; the other cracked so I threw it out). I have 6 pullets (9 months old) that lay regularly. They're all eating and drinking and pooping normally. These two eggs are from the same bird (based on color).

For context:
1.) Their litter is going to be completely removed and changed today. It's been smelling *a bit like ammonia for the last few days* and I finally have the time today to do a clean-out. It's several inches of pine shavings and I believe the spring thaw we've had has caused too much moisture to accumulate.
2.) They eat a 16% protein layer pellet, oyster shell free choice, fresh water to which I add a splash of ACV & electrolyte/vitamin powder every few days.
3.) They don't appear to be stressed, but I'm not certain. I see no signs of a predator invading their space and we haven't introduced any new birds.
*I'm concerned they may have developed a respiratory issue from this. I feel terribly that I allowed it to get like this and will remediate today.

Questions:
1.) At what point do I consider this a concern and not just a glitch? Another day, week, month?
2.) If there are no respiratory symptoms and the other girls' eggs are fine, could I rule out infectious bronchitis or avian flu?
3.) Is the only way to test for the above diseases to humanely euthanize and get a necropsy?
4.) Is there anything, apart from clearing out their stinky bedding, that I should be doing?

Thank you! As I said, I feel horrible about this. I've been trial-and-erroring with a deep bedding/litter method and obviously, it needs more cleaning out than I anticipated, as I know ammonia is a major No-Go w/ chicken coops.

some of my hens had wrinkles on their eggs in the beginning, since she is still under 1 she might just be working out some kinks. I think that 16% protein is minimum so upping that can't hurt.

Thank you! I did wonder if her young age might be a role. It just caught me off guard because they've been perfect until now.

Re: protein - is it possible/advisable to switch to a "feather fixer" or other higher protein feed altogether or should I do a blend of 16% and 18%? With increased protein, is there anything I should look for as a concern? I don't know much about chickens' dietary needs in terms of protein, etc.
 
I think that you can just switch over, I would go with an All Flock feed if you have it available. I think that mixing would be too much work, at least for me! 18% is just fine just make sure they have oyster shell as there won't be any added in that All Flock, grit and lots of fresh water.

Great info. 👍 Thanks!
 
Thanks! Of the causes listed, I hope it's not the first! It's possible she was frightened; sometimes small branches fall on the metal roof overnight and it can be loud. Also, I was out at night looking for my phone near the coop with a flashlight haha 🤷‍♀️. Not worried about overcrowding, as they have plenty of room. We are seeing more daylight, but not suddenly.

"Disease, such as infectious bronchitis;
- Stress, frights, and disturbances;
- Overcrowding in coop/run;
- Sudden large increase in daily light hours, for example, when supplementing light during winter months."

I'll keep an eye on things. At least I finished emptying their litter and putting new shavings in! Can't hurt.

Even though it isn't a sudden increase in lighting.. I think it COULD be the increasing daylight coupled with age causing the early release of the next follicle, basically a new layer hiccup.

But definitely keep an eye out for other clues. You already dealt with your ammonia issue.

Let me give a link to a veterinary resource with GUIDELINES (not absolutes) regarding protein content.. (that wasn't your cause but nutrition is always a good discussion)..

Thanks so much! I look forward to reading through the link you sent. Really appreciate it. Fingers crossed for just a new layer springtime hiccup! 🙂
