... where was your hens' successful hatching location? Did the hens sit in the woods, in a bush, somewhere else? And where did the unsuccessful hatches happen and how early/late in the hatch were the eggs predated?
Also does anyone else happen to have any stories of successful outdoor broody hatches? Or unsuccessful ones?
I've had chickens for about 18 months, and free-ranged them for about half that time--so, only one spring/summer. I had two that went broody with determination (i.e. hid their eggs when they discovered I was taking them): one American Game and Old English Game Bantam. Both of them successfully raised two clutches this year. The OEGB made a nest under the workshop/shed and hatched 7; the AG made a nest underneath the lawn mower, between the workshop/shed & the garden, and hatched 6.
The AG brought her chicks to the chicken yard area on day 3. I had prepared a large dog crate in a covered place with straw in case she wanted to use it, and she chose to take them in there every evening but free-range them during the day. When they were 6-8 weeks old, a hawk killed two; the remaining 4 are doing well.
The OEGB lost 2 to a hawk on the 2nd day. Because the bantam babies were so very tiny--and the mother barely a year old--I brought them all into a sheltered dog crate for several weeks while they grew a bit. The 5 that remained are still doing well.
Both of these hatched a 2nd clutch toward the end of the summer.
The AG laid her eggs in a cat carrier on the front porch of our house. I let her stay there until it was time for them to hatch, then put the carrier into an XL, covered, dog crate. After a day or two, the mom took them out of the crate to sleep under the doghouse. After one chick was lost to a snake, she decided the dog crate was safer and she began taking them in there to sleep every night.
The OEGB chose to make her 2nd nest in a nesting box and I let her stay there.
From my limited experience, I'd say that a little luck is involved, but success is mostly due to native mom-smarts.
