Worms?

[Eggcessive]

Sometimes we see soft or shell-less eggs in young new layers, or in old hens, as well as in the conditions seen above. Have a look at itsm number 10 in this link:

The vet that suggested the calcium supplement...did he test for worms at that time?

Are they getting a lot of greens. I am lead to believe that spinach/kale etc can prevent absorption of calcium. I regularly feed mine perpetual spinach with no egg shell issues, but some people are quite insistent that it can cause a problem.

I've fed my girls (4 BOs) Romaine lettuce leaves (est 4 - 6) every day, never had an issue with their egg shells. I do ferment Flock Raiser, they get grit & Oyster Shells on is separate dishes and some BOSS scattered at close up.

Thought Kale was "good" for them? Guess everything in moderation is ok? Always learning and loving it Thank you

This is the only thing I can find that kinda fits.
Not other symptoms but these shell less eggs right?

That's right, just the eggs. So if this is the case, it's a lifelong egg issue without other symptoms?

Thanks for the info!

That is the only thing I can find that has no other symptoms besides these type eggs.

It greens that are high in oxalic acid

"Oxalates are found in almost all plants, but some plants contain very high amounts while others have very little. Animal foods contain only trace amounts.

Foods high in oxalate (100–900 mg per serving) include:

• Beet greens
• Rhubarb
• Spinach
• Beets
• Swiss chard
• Endive
• Cocoa powder
• Kale
• Sweet potatoes
• Peanuts
• Turnip greens
• Star fruit"

Then there is this:

Also, birds fed too much BOSS; when the seeds break down for digestion, the oil is released into the digestive track coating the intestinal lining and preventing absorption of nutrients.
I'm not saying not to feed BOSS or any of the veggies mentioned in these links. Moderation is key when it comes to chickens.

I don't think OP feeds her birds anything besides layer feed.

I don't think diet is the problem here.
