My lovely chickens (Maude and Eleanor) used to go to bed in their coop each night with no complaints, but lately they've started roosting on the very top of their coop. I know that they feel safer up there, but is this really something I should encourage? They're young now, but they're going to start laying some day and I'm pretty sure eggs roll downhill. Should I physically put them to bed each night? Or install chicken dissuading technology on the peak? Also, they were both supposed to be Ameraucana, but Eleanor is quite a bit larger, with different coloring, and a different comb. Are these girls perhaps step-sisters instead?
