Well, a moderator told me not to let them sleep in the nestbox or I'll have poopy eggs. So, I'm being really good about this, and every evening at bedtime (for birdies) I plop them on the roost and they stay. I check on them before I hit the sack myself and they're still on the roost. Good! But in the a.m. the nest box was visited by one of them because there is poop in it, alot, so one of them is being sneaky. I know it is just one, because there is a poop pile below the roost. How do I correct this without going out there every hour to roost them? Or is that what I do? I only have the two, ages are about 17/18 wks old. Any advice?
