Can I get some opinions please. I have a total of 12 hens & pullets. 2 silkie roos. I currently have 2 coops, in 1 I have 2 hens & 2 pullets. In the other 8 pullets & the 2 roos. My 2 hens are about 1 1/2 years old. All the pullets are about 7 months old. The 2 in with the hens were laying. 3 of the other pullets were laying. 5 have never layed an egg. My 2 hens are molting so they are not laying. But all the pullets have quit laying also. They have free access to food & water. I did switch brands of food about 2 months ago. They have not laid in about a month. This was about the time the days started to get shorter. I don't use artificial light or heat. The coops are not drafty but do have good ventilation. Should I switch food again or do you think its just due to shorter days, or do I have an egg eater? Help please I miss my eggs & refuse to buy store eggs!! Thank you.
