Ugh. I'm pretty sure there is no "quick fix" for this problem, but I thought I'd ask around in case anyone had an idea I hadn't tried yet. My 5 pullets will be 18 weeks old tomorrow. They are starting to show signs that they are getting close to laying - comb and wattle growth, reddening in the combs and faces, and squatting - so I have opened up my nest boxes. One of them, my little Welsumer (who is my favorite in the group for her sweet personality), has decided to start sleeping in the nest boxes. I have a prefab coop, but a large one (around 54 square feet of floor space, not counting the nest boxes - and they have an additional 100 square feet of run space, plus are allowed to free range for around 1-3 hours every afternoon, depending on my schedule). There are about 12 linear feet of total roost space split between three separate roosts. After spending some time on these boards, I did some modifications on the coop to raise the roosts and increase ventilation, so I feel that the size and location of the roosts have been eliminated as possible problems. Four of the five pullets immediately took to their new, higher roosts, but Cora (the Welsumer) is not getting it. I've spent about 45 minutes every evening in the dark this weekend playing "musical chairs" with her. I take her out of the nest box and put her onto the roost, where she stays for a minute or two before hopping down and going back to the nest box. Lather, rinse, repeat. When she finally stays for several minutes, I leave, only to discover in the morning that she has obviously slept in the nest box (due to the feces and feathers she leaves behind). Is she just going to take longer than the others to figure this out? She's not getting bullied off the roosts, and even if she were, there are other roosts she could choose to utilize. I wait until it's so dark I nearly can't see the chickens to move her, and she still somehow finds her way off the roost and to the nest box. She's sleeping in one of four nest boxes. Should I just resign myself to allowing her to sleep in that one? Has anyone else every experienced this before? I adore this sweet little girl, but she is driving me crazy! Here's a picture of the offender. Isn't she cute? She's a bit plain and small compared to the rest of the flock, but I'm smitten anyway.
