Issues with my Easter eggers! I have two Easter eggers in my flock of four chickens. I purchased them from the IFA on 21st South a year and a half ago (Feb 14, 2010), where they were selling them as "Ameraucanas." One has been intermittently laying large, strangely-shaped eggs ever since she started laying. That bird has now started laying thin-shelled and shelless eggs, is laying only once or twice a week (if at all), and is sometimes laying them in the yard instead of in the nest box. Her behavior this week is off: not roosting on her usual perch, not eating (not even eating treats), sits down a lot in the yard and shuts her eyes, has really stinky poop stuck to the feathers below her vent (I clean this off, but she re-offends as soon as I put her back in the yard), etc. I was told by our vet that it's likely an oviduct issue with that bird. The remedy would be to remove the birds oviducts, which would end her egg laying days entirely.
Now I'm starting to have similar issues w/ my other Easter egger. I've found several thin-shelled and shelless eggs from her over the past couple of weeks, and she's only laying a couple times a week, if that. In fact, I haven't had a normal egg from her or the other EE for over two weeks.
To answer the inevitable questions - I feed my hens layer pellets w/ oyster shell mixed in. They roam the yard during the day, so they get bugs, food that drops from the bird feeders, and miscellaneous treats from our house. I upped the calcium-rich treats, but saw no improvement.
So, my question: Do any of you happen to have EE/Ameraucanas that you purchased from the IFA on 2100 South last winter? Are they having any egg issues this year? I'm starting to think it's a genetic issue and I got some bum hens.
One more thing to mention, my other laying hen is a Wellsummer. That bird stopped laying a couple weeks ago, too, but I think that is more weather related and she might be getting ready to molt. I'm yet to see a thin-shelled or shelless egg from her, so I'm not as worried about her health, but it bears mentioning since her egg laying ended at about the same time as the others'. I purchased her at the same time and place as the EEs.
