I decided to just let my broody do her thing. I marked her eggs so I'd know which were the ones being incubated. About wo days later, two of her eggs were smashed/eaten/missing, and there was a big wet mess in her nest and dried egg yolk all over the remaining 3 eggs. We don't have egg eaters, so I think it was an accident? So I fenced off her area with chicken wire so she could have her own area, with water and food in it, and some space to walk around. Put a few more eggs under her, and am prepared to incubate for the last day or so if she doesn't wait for them. All is going well, and her 6 eggs look fine so far.
This is my first time using a broody also. All the hens live in a covered run, and of course the broody had to pick the favorite nest box to brood in.
Success!!! My broody (Sassy) is now raising 3 chicks. They are about 2 weeks old.
Hatch date was on a Friday, first chick hatched on a Wednesday (2 days early!). Second chick hatched Friday. One egg with a partially developed chick got smashed on Friday or Saturday (I think it got halfway then stopped developing). On Saturday afternoon it seemed like Sassy wasn't sitting on the nest like she should be anymore, so I "rescued" the last three eggs. I could hear them cheeping, so I put them in the incubator. Once they got warm, the distressed cheeping stopped. Sunday morning baby 3 was born when we woke up. Sunday afternoon I got curious and made a safety hole where the air sac is to check on chick development - when I candled they didn't look right. Both remaining eggs had totally failed to develop, so I'm gonna say they were infertile. We had put fake eggs in Sassy's nest on Saturday after we removed the real ones, in case she decided to sit some more. It was a good thing I added more eggs after half of the first batch were smashed, two of the live chicks came from the second batch of eggs I added.
Sunday afternoon, I took the 3rd baby out to Sassy. The chick got cold and started cheeping in distress. Sassy started clucking to it. I crawled into the broody enclosure with the chick in my hand, and shoved it under Sassy while she was sitting on the nest with her other chicks. I then reached under her and removed the fake eggs. As soon as the baby got warm, total silence from both mom and baby. I watched for a while, and nobody moved much. Sasssy's other chicks appeared a bit and ate and drank and went back under mom. Chick 3 stayed under her the whole time. I scattered some scratch in the enclosure, and even that didn't get Sassy off the nest with her 3rd chick. Everyone went to bed.
So far everyone has been well. I was pretty shocked that integrating the 3rd chick was that easy. Sassy didn't peck me, and hasn't this whole time. Absolutely no problems getting her to accept the chick. It didn't bother her at all that I was shoving a chick under her, or pulling out eggs.
I opened the broody enclosure to the rest of the run this weekend, to see how Sassy would do with integration, and every other chicken we had had to come over and eat in the broody enclosure, and poke their nose about. When they got too close to the chicks, Sassy would attack them, pulling on their neck feathers, and jumping on their backs, and pecking them. I was super proud of her, and happy she was willing/able to defend her chicks. She's in the lower half of the pecking order, so I wondered how good she'd be able to defend her chicks, but she even went after the head hen and won.
Next weekend, I'll probably dismantle the broody enclosure and let them all be integrated. But so far, so good on brooding and hatching and integrating chicks using a broody hen.
