I stop egg laying by giving eggs to entice brooding (even fake ones). I stop brooding by sticking them in a wire bottom cage with feet and placing outdoors in shade when it's nice to do so.
I do the same, but the cycle continues. Continual brooding and egg laying has to have an effect on the bird-eventually.I've been told you can also give seramas a quarter tab of a baby aspirin to break broodiness. I tried once and the hen wasn't completely broken of it after her first dose. I think it would've worked eventually, the advice was given to me by a lifelong chicken keeper. But I just don't really care for pilling birds if I don't have to.
I agree. For me it's not so bad to just toss her in a cage for 3 days instead.
Then egg laying starts again. As for your earlier question about breeding micro seramas, I agree with
shahtir101 . My understanding is that when one pays attention to the size of the birds and pairs like with like, fertility improves.
