My girls are 11 months old RIR, and were laying for the last 5-6 months in the coop like clock work. It has been very cold here (midwest) so i have tried heat lamp - didn't work- girls stopped going in the coop when the light was on (temp timer) then i tried a heat pad and the girls stopped laying in that box so i stopped everything and this past few weeks I noticed feathers all over the inside coop so that might explain what is happening now with their egg hiding game. I let them free range when the temp is above 20-25 degrees. I also noticed they have not been laying eggs in the box so i just thought it was the cold weather and no sun. a few days ago I was checking their water and saw 4 eggs in the corner of the run covered in dry leaves - of course cracked frozen so i threw them in the compost. Yesterday found an egg in the middle of the run, today i found 5 eggs between 2 straw bales and only reason i looked was to get my hen out of there! Then this afternoon I saw one of the girls coming out of another corner of hay and so i knelt down and found an egg. Anyone have any clue what is going on?
