I had my first hatch with a broody hen a couple of weeks ago. My hen was extremely committed despite our lack of rooster, and a friend had eggs that her mama hen had left behind after hatching out 6 chicks so I gave them to my Mama. Because we've never had chicks in the coop I was nervous about it's layout and the other hens, so Mama and her nest were all placed in a seperate space that is attached to the coop but seperated by hardwire cloth. Mama had her first hatch sept 2 and then a second sept 5 and a third sept 8. I removed two remaining eggs because i was skeptical of how it would all play out with such a staggered hatch. Chick #3 made it about 5 days and looked great, just a bit less active than her older siblings, and then I found her dead. I'm guessing she got cold with Mama moving around more to show the other chicks the ropes...? In any case, now I'm definitely nervous about how to keep the two chicks remaining safe. Now I'm unsure how and when to make the transition from the seperate section of the coop to allowing them the freedom the rest of the flock has in the big coop and attached chicken yard. If I had my choice, I'd keep them sequestered as long as possible, but Mama is acting anxious and stressed. She's always at the open wire section looking in at the other hens in the larger coop. One of my concerns though is that it's getting chilly here as fall rolls in and I don't quite understand how the babes stay warm if wandering around in the coop and yard? And at will mama need to have a new nest? At what point do they babes roost with the rest of the flock? When will they be able to stay warm without huddling under Mama? Clearly I'm a novice and need some serious help.
