Is it normal

Here are my meat chickens

Large bird in first pic appears to be a mix...
....with either leghorn or cream legbar or something else with white earlobes.

What are you feeding them? Maybe to much calcium, I know it can cause REALLY thick shells and thick membrane so maybe it is a link

I feed them layer feed crumble from Tractor Supply

Purebreed what? If they are meat birds, maybe Red Ranger or Dixie Rainbow or some such thing?

They are Red Ranger

They are Red Ranger

Those are not exactly a 'pure breed', they're a custom cross bred specifically for production... very similar to Golden Comets, Production Reds, or ISA Browns for example...

Many birds bred for production produce double yolkers... some will off and on or regularly their whole lives...

Double yolks halves the amount of eggs a bird will lay in their life as well, since each female hatches with a finite amount of eggs within her ovary... once depleted they are gone..

I was told that were pure breed

Don't feel bad. I was told the same thing by Southern States. I ordered Rhode Island Reds & got Red Sex Links, & I was too new to know the difference 'til I got to digging around & asking questions here on BYC

I understand... but unless they are accepted by the APA as one, then they're not an actual breed...

Hatcheries are for profit... they produce chicks from breeds in mass quantity to supply a market... they also know they have to compete with other hatcheries... so coming up with custom hybrids, or reproducible, sustainable specialty birds to target specific needs/wants in the market is their goal... they experiment, come up with something new or a variation of something already out there, slap a label name on it and it becomes a new fad...
