After living on my front porch for the past 8 weeks, my beloved Mama Matilda seems to be done being a Mom. She's been- not really "ignoring" the chicks (who are 5wks old today), but definitely not fussing over them like she used to. I had them out free ranging on the front lawn today and twice I caught her wandering away without them. The last time, she had made it around the corner of the house, heading for the back yard. I went and opened the gate for her- she headed over to the rest of the "big girl" flock and never looked back... or so I thought. After awhile she started clucking, and pacing around the back door- like she was looking for something. SO- I picked her up & took her back to the chicks... where she promptly ignored them and started pacing back & forth like she wanted to go out. She didnt settle down, so I took her back outside. A few minutes later, she started clucking again. I grabbed a couple of the chicks & took them outside with her. She completely ignored them again- even when a couple of my other chickens came over to investigate them. They went back inside (she didnt care), she went and had a couple of skirmishes with the Alpha hen and the bottom-rung hen, and then went about her business. Now she's back at the door, clucking & pacing. WHAT DOES SHE WANT?!?! The other hens dont seem too fazed by her presence out there, but she's not exactly "part of the flock" anymore, either, so I'm not sure where she should sleep tonight. They're all out grazing & doing their chicken-thing, but she's off by herself, alternating between clucking & pacing and hunting & pecking in the dirt. Do I just wait & see where she goes on her own? I thought I'd need to reintroduce her via dog-crate-in-the-chicken-coop since she's been away for 2mos? If she goes to bed with the big girls, will she be okay in the morning when they all get up? Maybe I should leave the chicken door open so she can escape into the run if she needs to? Will the chicks be okay without her? Or should I give them a heat lamp with a low-watt bulb? The front porch stays pretty warm during the day, but gets down in the 40's at night. I dont want them to get cold. Thoughts??
