Im new to this chicken thing and TOTALLY loving it!! I have 4 mixed breed hens that were bought at the same time from the same place. Two of my gals are "older" and only one is laying. The other one, who happens to be the boss hen, has had poop on her tail feathers lately, the last week. All normal looking poop, nothing icky as far as i can tell.....I've read about all the stuff they can have, her behavior is normal. She eats, drinks, scratches the ground for bugs and loves attention....doesn't act sick at all....is she just messy? none of the others seem to be having an issue keeping clean. i scoop their coop at least 2 times a day.....and they free range all morning. another quick question....if 2 hens are aprox the same age, why is only one laying? Thanks for listening!
