I have a broody hen who is sitting on 8 eggs right now. I went out this morning to check on her and I noticed that she has some clear drainage around her beak and eye. I think she has a cold. Her top comb is very pale in color as she has been broody for over a month now. I just found some fertilized eggs last week and put them under her. Any suggestions on how I should treat her? Thanks for any information.
