You started giving oyster shell recently? You can try getting some liquid calcium to mix with water and offering it alongside a separate container of fresh water so they have a free choice between the two.
I’ve always had eggshells available. Always. There is oyster shells of all size in the sand I use for the coop floor. They have plenty of free access to calcium. What I’m wondering is if they actually are eating any of it. One leghorn’s egg is good and always has been. All the other hens have great shells.
I forgot to mention that 2 eggs had super thin shells about 4 days ago. On the same day of a broken/deflated shell. So 3 out of 4 leghorn eggs that day had shell issues. That’s when I decided to try adding calcium in the form of powdered eggshell to their feed. I did get the next day when 3 laid and all 3 shells were good but that success didn’t hold. So that’s when I added a feeder with layena pellets in it as a free choice for all the flock. I do see hens eating the layena but overall they strongly prefer the flock raiser crumbles. I do go thru the eggshells- the hens other than the leghorns eat the shells as they should.
I Don’t think the yesterday egg was pecked per say. The leghorns hog the nesting boxes until they are done. The other hens go
In quickly once the boxes are free and they do tend to roll the leghorn eggs out of the way. Maybe this action on a wet egg caused the ‘lines’? I do not think overall the other hens like the leghorns very much!
I too thought adding calcium where the leghorns couldn’t avoid it was the way to go. But I got serious pushback from someone when I mentioned the issue and what I tried on another thread. I’m hoping this thread dedicated to the question will give me the info I need to try to 1) address any underlying issue that may be present and 2) get the most eggs I can.
Oh. The leghorns I got on May 1. They had issues the previous owner didn’t disclose. I’ve fixed most of that but them having a low calcium reserve, so to speak, wasn’t immediately on my radar.
Ok. I’m Putting more of this together by posting. All
4 had significant feathering issues. The one with the least feather issue is also the one with no egg issues. They are all finally feathering in nicely. Maybe the eggshell issue WILL resolve After All
The feathering is completed...? They are getting the higher protein by eating the flock raiser but may also need more calcium and for whatever reasons they aren’t eating what they need even though it’s available thru 2 different ways (the eggshell feeder and the oyster shells in the sand floor).
But the bottom
Line is... they probably need to Intake more calcium
Than they have been to support not only the feathering but good laid eggs too... right?
