Malformed egg

[lisalovli]

Hello,
I have had a number of weird eggs laid lately but the attached picture is the most extreme example. Sorry, it is a bit gross.
Can anyone please advise what my chicken might be lacking to lay this type of egg? Or does she have worms? An internal problem? Similar bad eggs were more formed than this (I considered eating them) but they were still soft and had a funny twisted skin-type tag on top.
I’m not sure who is laying this egg. I have three Rhode Island Reds and two Wyandottes.
Thank you!

how old are your birds? Have they laid normal eggs before, or are these their first?

None are over 2 to 3 years old and all usually lay normal eggs. Thank you

That would suggest a calcium/vit d deficiency then; is it approaching the end of the laying season where you are?

We are in Australia so we are 2 months into the Summer season. All my girls eat the most expensive food from the feed store plus lots of fresh food and they free range in a very large garden area so I’m not sure why they’d be lacking in anything really. Any idea what I should feed specifically to help? Thank you so much.

I think the hens' stores of nutrients get depleted as the season wares on, no matter how good the feed - that's why commercial firms rest their birds, or indeed, even dispose of their stock when they get to the age your girls are. So it sounds like you're not doing anything wrong, they just need a rest, and their systems are beginning to fail. Once they've had a moult and a well deserved rest I imagine all will be back to normal!

An internal problem?

This looks like lash material inside the 'tube'.
If you still have this, slice the 'tube' lengthwise and take another pics or two.

Is your weather unusually hot?

A glitch or two is nothing to worry about, but with a persistent pattern of oddities, especially from the same hen, there's some kind of problem involved that may or may not be treatable.
