Thanks for your help everyone. I'll continue to keep an eye on her but if she doesn't start laying in the next few weeks or if she shows signs she's worsening, I'll make a call on dispatch as the birds are purely for eggs.
One of my 18 month Y/O White Star chickens hasn't laid in weeks and this morning I noticed that she laid a soft shell egg like I've never seen before (see picture) and she's had poop around her bum for a few days.
She doesn't look underweight, is moving around ok, though has just gone back into...
