My two dark brahma hens started laying eggs in January 2014 and kept it up until they started molting - one in August, the other in September. We went about 3 months without homegrown eggs, then Tilly started laying again on Christmas Eve. Hilary started laying again a couple of weeks later. For a few days I was getting two eggs a day. Then, suddenly, Hilary started choosing to roost in the nest box at night. I changed out the shavings and that seemed to do the trick. But, that didn't last long and then Tilly stopped laying, after laying for only three weeks. I now block the nest box at night, with a piece of cardboard and remove it before the sun comes up. Hilary is forced to roost on the roosting bar instead, and judging by the positions of the poop piles under the roost in the mornings, that is working -- until the next night when the daylight goes away and they put themselves to bed, and Hilary takes the box again. It has become routine to go out and move her to the roost, then block the box for the night. In the mean time, Tilly has not only stopped laying, but no longer squats when I reach to pet her. Both girls free range in the daytime, and the only time I ever see them not together is when Hilary goes in to lay her egg (every other day). Once she's done, she is right back out with Tilly. So, I have several questions about all of this. Firstly, could it be that Tilly's not laying anymore, after starting up again for three weeks, and Hilary's using the nest box at night are related? Secondly, this time last year, they were both laying almost every day. Last year it was very cold here and we had snow and ice. This year, the weather is very different and it has been warm - up to 60F in the daytime sometimes. Usually in the 50s. So, because Brahmas are a good winter layer, could it be that it isn't cold enough for Tilly to be laying and Hilary to be laying full time? Thirdly, these are my first hens and I know zero about broodiness. If Hilary lays her egg and spends the rest of her day with Tilly, foraging, does her choosing the nest box only at night -- with no eggs in the nest -- sound like broodiness? Fourthly, is there something I can do differently to "train" Hilary not to sleep in the nest box? Or should I just keep up with the cardboard blockade? Lastly, Tilly isn't acting sick or anything and she looks great. She just isn't laying anymore after starting up again for those few weeks. Should I be worrying about her? Is there anything I can do to help her start laying again or just wait it out? I do not use artificial lighting and do not want to use it. Days are getting longer now anyway, and she was laying great guns at this time last year. Sorry to be so long winded. Any help and advice is appreciated. Thanks.
