I have 3 turkey hens in with one tom. During the day they are loose and I pen them up at night. I made a nest for them last week out of a very large oval plastic tub with straw in it. It's on top of an upended doghouse to keep my two pot belly pigs from getting the eggs. So far the hens have laid 7 eggs in it, but don't appear to be setting on them. Is this normal? The temps have been down in the low 30s at night at times and I'm worried the eggs are no longer viable. Should I try to bring the eggs in and incubate them, or is it too late? I really, really would love to have some poults this summer. Thanks for any advice.
