Jumbo (?) eggs

[Ylva]

Two of my five hens (a Black Copper Marans and a silverudds/Brahma+Plymouth Rock mix) lay really large eggs (72-74 g / ~2,55-2,58 oz). They are too large for a regular egg carton. Is this common? The mix isn’t a particularly large hen, is it potentially dangerous or painful for her?

Have you cracked them open? They may be double yokers.

They have laid 72-74 g eggs almost daily for months, and no double yokers.

A chicken's pelvis is not like your pelvis. Look it up. No pelvic ring. No, its not normally dangerous, though I'm surprised a Brahma-mix is involved, they aren't famed for unsually large eggs.

Some of the most productive and prolific commercial layers of XL eggs are quite small birds - the various production red sex links tend to come in between 3.5 - 4.5# as full grown hens (1.6-2kg). I imagine both your birds are significantly larger than that - or certainly will be when full grown.

You could change their feed.

Sometimes high protein does that.
