Hi Mumsy, I feed my shells back too. That's too bad about Phoebe! I hope she does okay. What did you mean by pinched tails? Do you have a picture of this?I feed back all egg shells to my flock and they free range fourteen hours a day or more. I do not supplement calcium. Oyster shells are indeed on my beaches here but not naturally in my yard. The eggs are all firm and hard shelled on all that are laying. Even the Silkie eggs are tough little things.
The two light colored hens in the middle are out of project pens meant to be broilers. I bought them at a show last year. I think they are Orpington crossed. The black hen with the Silkie chick is Judy the Broody. The two red production pullets are daughters of Phoebe. Those two buff hens lay large eggs nearly everyday but both have pinched tails. A bad confirmation trait for layers no matter what the breed. I knew from those pinched tails these girls will eventually have problems. Phoebe's problems have been escalating since day one.
You're welcome kpchick! I work with a lot of older gentleman who have to use a computer for work but aren't always comfortable with technology. We hire a lot of retirees. I'm always creating instructions like these. Glad you found it helpful!!Thanks for this! I'm electronically challenged and can't really figure out how to post but now I'll keep trying!!!
