All my hens were laying like crazy. Then a few were laying off a bit and now only 2 are laying regularly. I have 6 hens of different breedings. I checked 2 of them today that are not laying; it's been 2 months for my Cocoo Maran and about 3 weeks for my Buff Op. They did not have any mites or lice but there combs are very pale now. They were very red while laying well. The little Buff is always being bullied, not to the bleeding or feather pulling but she's alone most of the time and on a roost alone at night. Her eggs have always been very soft shelled and she's always had a poopy butt. I am thinking that I should go ahead and worm all my girls. What is the best wormer? I've used DE food grade a little in pellets but not anything else. I use DE on them occasionally to make sure they don't have mites and I put it on the roost boards, and it's in the dust bath which is available to them daily. Any suggestions would be appreciated. I was getting 6-7 eggs a day and i"m down to 1 or 2 now. I do have a timed light, feed oyster shells are free fed, some good scratch one time a day thrown outside and an organic pellet feed. They always have water but haven't tried vinegar in it which I'm thinking about. They get some scraps but usually just some greens.
