Old bird egg or stressed bird egg

[City Farmer Jim]

I have a question for the great minds here at BYC...I have a picture of an egg likes of which I have never seen. It has been extremely hot in south Texas since April but were getting about normal amount of eggs considering the conditions BUT RECENTLY the last 45 ish days we have been getting extremely thin shell to no shell(basically just the membrane) for about 3 weeks, I/we have switched to mini pellets 16g% layer feed from TSC about 45 to 60 days ago. I AM going to the feed store and get our "normal feed" tomorrow and WILL NOT go to TSC for at least 6 months as a trial of feed. Our flock is a mixed age flock 4 will be 4 in the spring 4 will be 3 in the spring and 4 will be 2 in the spring. Mixed breeds orpingtons, silver, gold laced and blue Wyandottes, Americanasand Astrolorps.

I would guess heat stress and the food change contributes to this.Your chickens are not so old that they should be laying weird eggs just from age.

What brand and model of feeds?
Did you check the MFG dates on the feeds?
Just naming the store is not good data.

Do you provide extra oyster shells?

Could just be the normal ramping down of production with the shortening days.
Not unusual to get funky eggs at that time.
