My 4 month old Light Brahma hen was fine until this morning; she did not run outside to the chicken yard when l let everyone else out. She is just standing in a corner of the hen house. l offered her some scrambled eggs- would not touch them!! She will neither eat nor drink. l picked her up to examine her and some clear, warm water (?) came out of her mouth. What in the world is going on?? Please help! This is too weird.
