I have an 18 month old speckledy hen (Rhode Island Red crossed with a Maran). I've had pretty much an egg a day from her since she started laying as a pullet. About 2 months ago she's stopped laying.
A couple of times after she first stopped laying i remember looking into the coop at night to check they'd all put themselves to bed and they'd be a soft shelled egg under the perch were she was roosting Thought it was a bit odd but just cleaned it up each time and didn't think anything more. About a week ago i was in the garden and my leghorn was running about with an egg membrane and all the others were chasing her about, i looked under the bush where they were all chilling before all the commotion and there was an egg white and yolk by were my speckledy was still standing. They've never laid anywhere other than the nest box before. So in total i think she's laid about 4 soft shelled eggs in about 1 1/2-2 months, other than that, nothing.
She's acting fine, looking good, acting exactly as before when she was laying. I have caught her going into the nest box a couple of times during the afternoon and sitting there for about 20 minutes and then coming out and carrying on with the usual. She's never been broody or had a moult before, but she's not spending time in the coop during the day and she's not losing any feathers.
My chickens are free range, have woodland, grassy lawns, plenty of soil to dig in, sandy areas to dust bath in (which she was doing yesterday). I give them layers pellets in the morning and then corn/maize in the evening, water which i put ACV with mother in and once a month i do a week of Nettex Vit Boost + Poultry Tonic with Added Seaweed, they also have a dish of oyster shell. They're all wormed with flubenvet every 3 months.
Any help with this would be great,
Thanks in advance
