Hello Nancy and welcome to Backyard Chickens! It is a pleasure to have you and nice to meet you, wishing you a happy and healthy New Year. As far as it goes with your question concerning bumblefoot, it is not an issue I've delt with in my flock but I hope your hen cures up quickly for you. You will not catch anything from the eggs your hen had laid, the ovary system is different from the nerve system which means that her eggs will be edible and fine to eat. (I am no expert but hope this helps). Good luck and God bless! By the way, thank you @Better Than Rubies for mentioning me.
