I have a 5 1/2 month old BO who just started laying a few weeks ago. I have a BR the same age who hasn't yet and a 10 wk old RIR and a 10 wk old Polish. I had asked advice when my BO started to lay about food because of the age difference. I followed the advice and have kept all four chickens on grower and supplement on oyster shells (which they show little interest in). That's the background info and here's the question......... The first egg was huge and she laid a small egg every day for the next week and a half. For the next three days she laid a shell-less egg each day. Not an egg with a leathery shell like i read on another post. They looked like i cracked it open on the ground. I fed her some egg shells which i baked and now she hasn't laid an egg since the shell-less ones. It's been about a week. Is this normal or is there something i should be supplementing her diet with? Any advice would be great.
