A new hen just a couple months old has started to get poop stuck to her bottom. Before this one of our oldest chickens who was very slowly dying had lost feathers and had poop all over her bum and she mixed with our less old chickens and the newest flock because all her friends died and we thought she just had to be with the other, but this chicks name is Ruby. There has been several occasions where she just lays a soft egg in the middle of the yard even though she knows where to go to lay eggs. She once even laid a soft shell during the night.
We think that she may just need to be wormed, but the vets around where we live haven't got any worming stuff in and wont have for a while, they said. does anyone know what she has and/or what can help Ruby?
P.S. She hasn't laid soft shell eggs for a while, then started laying huge eggs (80g or more) but still has poop stuck to her bottom, just wondering if there's something that can stop her from doing that?
