Back story we started out with 9 hens and 1 rooster but due to stray dogs are down to 6 hens and 1 rooster. We went from 5 or 6 eggs a day to 3 or 4 and now 1 to 2 tops and more like 1 egg every other day. We do live in the midwest so it is winter time here and colder so I expected less eggs but now my fake eggs are missing from my coop too. We originally had them there to keep the girls laying in the nesters. We have 3 dogs, a goat and a cat but the goat and dogs do not bother our hens. It could be the cat but we have never seen anything left like shells etc. Going to not let the girls leave the coop tomorrow being they are free range and going to look for shells and fake eggs. Girls are 1 year old so should have eggs; any advice is appreciated.
