If you're worried about accidentally killing chicks, wait until you're ready to throw eggs out anyway.I don’t think I’m brave enough for that
If you're worried about smell, do it outside. But if they were going to really stink, you would be smelling something just as you handle the eggs. So I don't think they will be too smelly.
Roosters can have favorite hens and ignore others, but with that many different hens I would have expected him to mate with at least SOME of them!These are all from four different hens so I’m wondering what could be happening.
