Dear Lady of McCamley I Have decided to move the date to the 5 of march as trying to break her failed I put her in this morning and I came back just now and she is broody on the metal wire and has plucked some more chest feathers of her self do you think 3 weeks and 2 days will. Be ok I will be taking her out to eat and drink everyday also shutting her out so she can get some exercise also I did feel a bit sorry for her when I had to put her in the cage and she was so excited when I bought her back to the coop she ran to her fave nest and settled down and also you were right If I was to break her now she may never try to go broody again or if she does she may be a bad Mama Thanks for your advice Cc999
Broody hens get up to eat, drink and exercise once a day. You don't need to do that for them. They are very capable of brooding and staying healthy as long as you provide access to their needs. You will likely not see her get up is all, so it looks like she is always sitting...but that is what broodies do...incubate eggs keeping the temperature constant...that requires a lot of sitting. It is nature's way. To help my broodies, espeically if they have been on an extended brood, I like to put Vitamins and Electrolytes in the water (like "Save A Chick") and switch them to a high protein feed (like unmedicated Chick Starter or Flock Raiser at 20% protein). This helps them keep their reserves up. I also add yogurt or ACV, some nummy treats (high protein), close by. I essentially reward them for doing a very valuable service for me.
Therefore, in your situation, I would recommend putting her in a nice nest with food and water accessible (but not so it can tip into the nest), make sure she is protected from others, has room to stretch her legs when SHE feels like it, and let nature take its course. If she is still sitting nicely when you have fertile eggs, then put them under her.
I believe that the more you intervene now, the more likely you will upset your bird and possibly interfere with natural processes....especially if you want her to brood for you faithfully. You may not prevent her from brooding, but you can definitely interrupt her body cycle enough to where she does not sit continuously as she should once she gets those eggs. You are essentially discouraging that by picking her up and locking her out.
As to your 3 weeks and 2 days question...I can't tell you with certainty if she will brood beyond that or not. Each bird is unique. I can only relate my experiences and my understanding of broodies. Those that are diligently broody (typically your faithful type Silkies) will brood until they hatch chicks however long that takes (The average time is about 5 weeks, but it can be longer or shorter). I have had one of my faithful broodies go into a brood and was not able to put eggs under until about 2, maybe 3 weeks, maybe even later...I hadn't had access to fertile eggs and was hoping she would naturally be done as I was busy with other things, but she tarried in her brood until she finally convinced me she wanted to be a mother no matter what my schedule said. She sat and hatched 3 out of 5 eggs for me (2 were infertile), and mothered them well.
So if she is a typical very broody Silkie, it is likely she will complete the process until she gets chicks, especially as she feels the chicks growing and hears the chicks moving in the eggs.
And if you let her have her natural way, she will likely become a faithful broody for you such that you can count on her to brood when you need her...taking in mind her schedule more than yours as you adjust to nature's timing. And that is a good thing...because when you let them go about their business, they become such faithful brooders that you can use them to save eggs another hen has abandoned, and you can put foster chicks under them at a moment's notice. I treat my broodies like the queens they are, and it pays off.
Good Luck with your flock
Lady of McCamley
