I take the rails out during lockdown. I only use rails for holding sponges at the back.Thanks ladycat! Do you leave the spacers in when your hatching or take them out and lay eggs down? Probably a stupid question but I don't know a single person who has hatched eggs before so have had to garner the majority of my information online.
I decided to make it into a blog post. You can see it here: http://agricommunity.com/2014/11/the-brinsea-goes-into-lockdown/When the current batch of eggs go into lockdown in about 8 days, I'll take pics to show how I do it all.
