My hen went broody today, and I'm separating her from the rest of the flock on Sunday! Super excited! Question though, has anyone ever had issues when a large hen hatches out bantam and large chicks?? I want more banties, but my hens never go broody, but I also need a few more layers. If I put both under her, will there be any issues?
I have had both hatch out in the same group with no problems, however, you will want to watch to make sure the littlest ones aren't trompled around the food dish or don't get constantly pushed out of the way when the broody is finding goodies for them while foraging. I don't interfere with the natural pecking order that is established even in the youngest group, but I will pull the littlest ones out once in a while and give them treats separate of the others so I am sure they are getting enough. Doing this a couple of minutes a day also allows me to keep track of their general body condition so if they start to look skinny or lethargic I could intervene if needed.
The other thing to consider is that often banty eggs seem to hatch a day or so quicker than large fowl eggs.... this isn't always the case but it could happen. In a normal clutch this wont be a problem because it would still keep the hatches all within a 48 to 72 hour time frame, but if you aren't careful to set all the eggs at one time you may cause a more extended hatch than you plan to. I wouldn't worry about the day early thing much otherwise, to me it gives the littlest chicks a chance to be out, dry and motivating before their bigger sibs hatch and start running roughshod through the nest. I would rather have the banties hatch early for that reason.
