I have a hen that has been standing around with her head drawn in and her eyes closed also her face is quite pale. The hen is about 1 to 1 1/2 years old and recently hatched a brood of chicks.
The red one is the one that is sick I posted the other pic for comparison purposes.
The reason I ask is because I have lost two birds before to what I think was colibacillosis but I am not sure so any advise would be very much appreciated. Thanks in advance.
