I have a Showgirl that is going on 14 days sitting on some fertilized eggs from other hens. I am currently incubating eggs inside that are on day 16. I am new to allowing a hen to sit on eggs so I am not sure what I need to be doing for her in the coop. During the past 2 weeks, I have had to collect eggs from under her that I know were laid by other hens and I do this everyday, collecting them for eating that is. I have her eggs that she has been sitting on marked. Anyhow, I am new to this, was not really planning on a hen sitting on eggs since I have been incubating myself. So here is where I need advice. 1. Her eggs are poopy dirty, do I need to do anything about this? 2. All my nest boxes are about 3 feet off the ground, do I need to re locate her somewhere else with the eggs so when they hatch the babies dont fall down? 3. I have an 8' x 12' Chicken coop, total of 13 Chickens in there, very large back yard that the get to free range in every day. What kind of preparations do I need to do before my showgirls eggs hatch? Any other advice or links with information would be greatly appreciated..
