Ahhh, it may have been the time of year then

with winter comes shorter days that indicate to the birds to stop laying because it's not good weather for breeding.
People can simulate breeding time by adding a light on for 14? hours a day. Be aware that it will burn out your hens faster.
How many hours a day have you been keeping the light on for them?
The mice scurrying at night can stress them out, here's my story of chicken stressed by a rat lol - my chickens started laying last January and have been laying steady for exactly a year with no additional lighting and it's winter in Canada, lol. We noticed a drop in egg production about two weeks ago - the same time we estimate a rat hopped in the coop and has been living in the run and hiding corn under their hay under their roost and digging holes. We confirmed this yesterday and it answers why our girls slowed down on their eggs.
The rat must have been wandering outside the coop every night unable to get in. Then we put plastic sheeting all over the run, covering the hardware cloth. This funneled the smell of the food and treats at the open door.
We let the girls out one nice winter day, it got dark and they roosted themselves by hopping a few feet up into the door to the run. The rat made its rounds and didn't smell much from the tarp but there was all the smell coming from the open door a few feet up so it climbed up and in and seems to either like it in there or can't find its way back out
We've been setting a live trap and just tried to flush it out of its hole but it was already gone somewhere in the coop/run so the hunt is still on!!
It literally poked its head out to grab some cauliflower I just threw in the run. I know this sounds horrible but if we can't trap it I think we may have the Neighbour come over with his BB gun and throw some cauliflower in there..... :/
It's like we literally have a pet rat!!! Lmao
