while bringing in the little ones from their 'lawn time' yesterday, i noticed one of them had a bit of a bald area at the back and their vent was pulsating (for lack of a better word) ive never seen this on a chicken before..is it a sign of something being wrong? also my 2 year old marans hen has a big bald patch on the side of her neck..could this be caused by another chicken pecking her? many thanks also while im here can i ask..can a chicken 'break' its tail? one 9 week old hens tail has started leaning to one side, so much now that it sticks at a 90 degree angle from her body. it starts at the base (where the tail meets the body) and sticks out to the side. could this be a deformity or an injury? and if injury..can i do anything for her?
