I'm lucky in that the broody hen is already away from the other chickens. She is a silkie and was being attacked by my NH Reds so I brought her to my house instead of my land where my other chickens are. She lives in our backyard with my 2 dogs and we converted a nice wood doghouse into a henhouse for her. She is 10 months old and has only been laying for a month but about 5 days ago I could tell something was going on when she refused to leave her nesting box and would only get up once or twice a day to eat and drink. So I brought 3 easter egger eggs over for her to hatch. She's been sitting on them now for 3 days. I was not positive they were fertilized but my roo is very active with his 11 hens and I don't think I've ever cracked an egg open that wasn't fertilized so I'm hoping these all are.
My question is, say 25 or 30 days go by and these do not hatch. Is it dangerous to bring more fertile eggs over for her to try and hatch? Or is that too much time for her to spend sitting in the nest box? What do I do if none of these hatch and I can't put more eggs under her? Do I just have to make her get out of the box everyday and move on with no chicks?
I would not want to try sneaking chicks under her in case she rejected them. I've got chickens in 2 locations and a 4 year old and 2 year old, I would not be able to raise the chicks myself, no extra time. I plan on always letting nature do the work for me.
