alright so here is the story of her just so you know shes pretty special to me. i had 8 barred rocks. one night i counted 9 i was very confused had no clue why i kept counting 9 so had my husband come out and count he counted the same. some how i acumulated an extra chicken in my coop no clue where she came from but she didnt want to leave. shes had a tough time tring to find her place in my flock. them not being very nice to this new comer she got pecked on alot. now that you know she my mystery chicken. yesterday i noticed her bum was a little red so i took a little closer look and thought maybe it looks that way because she was a little muddy. and didnt pay that much mind to her the rest of the day today as i was doing my chores i noticed her foot was swollen and her bum was even more red then yesterday. i grabbed her and put her in a very warm tub and sooked her in some ESalts to see if that at all would help as i was dring her off i knoticed a hole in the bottom of her foot. but her bum looks much better she had to very good poops very big in the tub and one on the towle (the size of my broody hens poos..HUGE!!) i dont know what to do or think im worryed im going to have to cull her. for she adopted us. and ive never heard a chicken doing that. HELP!! am i over reacting or is something really wrong with her what do you suggest i do? couldnt get a good shot of her bum but this will be good i hope Edit also i forgot to say we had a dog attack our flock about three days ago.
