I have a broody girl with eggs under her, and other hens get in there and lay their eggs too, for her to brood. I've marked the initial ones to keep in there and am removing the additional. But, I'm having a problem in that one of my older girls is laying soft shelled or thin shelled eggs, and doing so in the broody nest. Today I had to remove all of the nesting material and replace it, because there was a big mess from a broken egg. The mess is also all over the other eggs. So, my question is, will this harm the incubating eggs or the broody hen sitting on them? Should I try to clean off the incubating eggs? Thanks for any advice!
