Great information. Thank you and so sorry to hear about your dear Nellie. She looks just like my Agatha ("Aggy-Waggy"). Just like you mentioned, she's had bad genetics from the start and always stuggled with laying.
It was such a relief to find this article and to know how easy it is to make a Calcium shot. Saves money and time that could be going directly to our feathered girls! Thank you! Berrywood House Hens
