My hens have been traumatized by wild birds getting trapped in the run & coop for two days now. I'm pretty sure I've secured the run/coop by covering all possible entryways. BUT it is full of the wild bird droppings. I'm concerned that my hens will contract something from the poop or just being near the wild birds (lice, etc). Unfortunately I cannot remove all the droppings without doing some major disassembly of the structure, not til Spring anyway. Should I be pro-active and treat them NOW for any possible disease or parasite infestation? And if so, what do you recommend? Thanks, I appreciate any suggestion.
