My arachs are the only ones with new chicks too. I wonder if they send out their chicks before they spend their energy on building summer webs?
Wll the configure stress the plant? I'm just wondering if you're more likely to trigger flowering if it has to work hard to produce all the extra chicks? If thats likely it might be worth detatching them early to preven them all flowering, as we saw in a different thread not so long ago.
