I've got 3 broody Cochin hens that are determined to sit on eggs -- EVERYBODY's eggs! I've set up a separate pen for them now with a roof on it, but I'm stumped as to what to use for nest boxes. Hubs says a five-gallon bucket on its side would be fine, but I think it's WAY too small for a big-butt hen, never mind her eggs (I think she'll break them trying to get into the bucket!) Also, this inseparable trio seem to want to sit on the eggs together --- should I let them? Any suggestions? Thanks!
