I have a silky that went broody about 2 mths. ago. At first I didn't give her any eggs thinking she would break her broodiness. Then when she wouldn't quit setting on her invisible eggs I caved and ordered some BLC Marans eggs. I put all 7 under her. She's in a coop with 4 two month old chicks another silky hen and a silky rooster, so they are all pretty small chickens. It has now been 24 days and nothing has hatched and she is still sitting tight as ever. I'm having my doubts as to anything hatching. I was gona pull the eggs from her tonight, but my question is this. I have 1 BLRW hen that is laying and I am wanting to try and hatch a few of her eggs, just in case something happens to her so that I still have a hen or two to fall back on. would it be detrimental to my silky to give her a couple new eggs to sit on for another 3 wk, since she has been sitting so long already? I have a feeling she is going to sit anyway. I think she is a little crazy for sitting this long, but I never seen such a determined chicken want to be a mommy. I'd like her to take a break but I doubt she'l quit, so what is your opinion as to how long should a silky be left to sit?
