I have this one Isa Brown hen, Pricilla, who is 34 weeks old, she has been laying for 15 weeks. She started out a good layer, good hard shells, no problems at all.

Fast forward till, I guess start of November or there abouts and issues started.

Of a morning I kept finding a shellless egg under the roost, just the soft membrane and egg guts, She would then spend half the day in and out of the nest box trying to lay an egg.

On the days there was no egg under the roost, there would be either a really soft shelled blood stained egg or a hard blood stained egg. Also the eggs she lays vary from brown to a really light brown in colour. She probably drops about 3 eggs a week from the roost and lays 4 eggs a week in the nest box.

She is on a 17% protien layer mix, gets meal worms every second day, has access to shell grit, scratch mix on the day’s opposite the meal worms, wormed and is due for worming on 1/1/2020, dusted for mites and is due 1/1/2020. Has access to a grassed area for free range, has a huge area to roam/dig/dust about in during the day.

There are 4 other hens she lives with, they all get on really well and the others are laying fine with no issues.

When the issue first started, I started giving her a wet mash with ground up egg shell to toughen her eggs, thought she may have been lacking calcium, but over a month later, the issue is still there.

I have checked her rear and no blood or issues there, and she isn’t being picked on either.

Here is a picture of 2 of her 3 eggs from the last three days, when you rub it with a wet cloth, the red comes off, so it isn’t a defect in the shell, it is on the shell. These ones are quite a bit solider than what she usually lays, I didn’t put my thumb through them when I cleaned them off. The third egg was a crushed when I picked it up it was that soft.

She lays regular, doesn’t miss a beat.

Ok, so I think I have provided all the information needed, Any help would be great.

thanks

Some birds just don't uptake and apply the calcium they consume as well as others.
High production breeds are more likely to have repro problems.
You could try to give her more calcium supplements,
@azygous has detailed info on the what and how.
Maybe she will come along and give that info
(or put it in an article so I don't have to tag her all the time :D )

Thanks for your reply, I will check back in the am to see if @azygous has responded and see if she can offer any help.

Thanks again
 
What is shell grit?
a calcium source, or a grit? We have ground up oyster shell here for calcium, and grit is different, they are not interchangeable.
 
Azygous just woke up, had to get a fire going in the wood stove so her fingers don't freeze (and her other parts), and tea brewing.

So, this is most likely just a temporary glitch in a young layer, and from the sound of her diet, she could use more protein as well as calcium therapy.

It begins with the poor calcium uptake as @aart mentioned. That can cause soft shell eggs, and when one of those runs through a hen's system, it's uncomfortable as well as potentially dangerous since it is more apt to get stuck and collapse inside her. Passing such an egg probably sets up a different sort of contractions that linger after the egg is passed, so you will find such a hen on the nest for a time following a soft egg, even though she's already passed it.

However, regardless whether you think all the egg has been expelled, there's great benefit from starting a regimen of calcium supplement, as you would take, as soon as you see an abnormal egg or abnormal egg laying behavior. Often, this "resets" a hen's egg production so it reverts to normal, and if there are any residual egg bits left in her, it strengthens contractions so she can expel the remnants.

Just get some people calcium such as calcium citrate or gluconate and pop the whole pill right into her beak. Do this once a day for up to a month or as long as it takes to restore her system to producing normal eggs. It may take only a week.

Since egg shells are heavy on the proteins, too, extra protein in the form of a 20% protein feed would be desirable in addition to providing calcium carbonate in the form of oyster shell, as a free choice.

Yeah is it the oyster shell stuff, It is just called shell grit at the pet shop down this way.

Thank you so much for your reply, I will have to look around for a 20% feed, the grit they are getting is crushed oyster shells, the pet shop has it labeled as “shell grit” they have the grit too and it is an actual grit, brought somewhere else.



I will get get some of the calcium tablets today and see how we go

thanks again
 
You could try feeding them a handfull of sunflower seeds a day for the extra protein or maybe a different source of extra protein like fish guts.....

Thanks...there are sunflower seeds in the scratch mix, but I will duck down town and grab a bag of just sunflower seeds.....I don’t think I can go as far as fish guts though :sick Could I do the rest of the fish? Like tuna, sardines ect?
 
I don't know if the pundits would ok this, but I give mine a little kitten chow to supplement protein.
