The last five days one of our chickens has been dropping her egg during the night while on the roost. Are there any suggestions of what we can do to get her back on schedule. We have 11 with 9 being Red Sex Linked and 2 Bard Rocks. They started laying in August and we had this problem with one early on but everything has been going well with all using the nesting boxes until five days ago when one starting dropping bombs at night. I am assuming it is the same chicken because the egg is always in the same place on the floor each morning. For background: we built 8 nesting boxes on the wall of the walk-in coop and they would not use them; we removed the dividers and made them into 4 boxes and they would only ocassionally use one but they prefer the cardboard produce box that is on the floor of the coop. All nesting boxes (including the cardboard box) have hay in them for nesting. We came to using the cardboard box because they started nesting out in the yard so we grabbed a handy box we had from a trip to Sam's <grin> and put some hay into it and they used it exclusively.....go figure. We then built the nesting boxes in the coop but they continued to use the produce box so we moved it into the coop and they are very happy. I think now that they are in full production (6-10 eggs a day) the one box may not be sufficient because I have seen two chickens in the box with one waiting in line outside to use it. I rigged another box for them but they seem married to the original one. So, could the problem be that this one chicken is not alpha enough to get her time in that box? Should I remove the box and thereby force them to use the built-in nesting boxes? What can I do to make the built-in boxes more desirable to the chickens? We love our girls and want them to be happy. Each egg is a miracle and I hate to have one being destroyed when I am probably causing it to happen by my lack of chicken management skills. Any suggestions? Thank you in advance for your time and help.
