Ok so she has still not 'got over it' as I hoped she would. I have, everyday, been dutifully picking her up removing the eggs as soon as possible and then putting her in the run where she usually has something to eat. Then she goes back into the house and nest box and pretends the eggs are still there until about 3pmish - it doesn't matter how many times I turf her out! But eventually, of her own accord, she starts acting like a normal chicken again - until the following morning. She has still been laying and hasn't pulled any feathers out or anything, and like I say, usually gives up towards the end of the day!
That was until yesterday when I inadvertantly seem to have made things worse by cleaning them out!! I plonked her in the run after much squarking and grumbling as per usual. I then cleaned their house out - pop hole blocked off so they couldn't get in. I thought it might help if she couldn't get back into the house for a bit - stretch her legs etc. By the time I'd finished she was under the house and had made herself a little nest under there. No worries I thought, by about 3pm she'll be back to normal...wrong!! She sat under there all afternoon and what I didn't realise until this morning was she'd been out there all night too!
Being black I didn't see her and just presumed she'd gone to bed with the others.
So my plan of attack today is that I will let the 'good' girls into the extension run and then block that off, get her out from under the house and shove her in there with them for a good while - with no-where to hide may be she'll forget about sitting?
I'm off to stay with a friend for a few days tomorrow eve and have a neighbour coming to look after them - I didn't want him to have to fight her for the eggs everyday but it looks like he's going to have to.
So how long will it take her to get the idea that eggs are not for sitting on? Anything else I can do? She's been like this for just over a week now.
