we aquired a 7week old astralorp yesterday because we needed addtl chicken for our coop. we have 3 - 6 week gold lace wyandottes. the new chicken seemed to be very mellow yesterday and timid. however, she did drink, eat the medicate food and scratched in the sand; also looked to be eating grass and dandlions. however, she also spent a great deal of time just standing in one place, very puffed out - looks like she has no neck - eyes closed. today my husband came from school to find that she had not come outside, but was still standing in similar pose inside coop. he brought her outside and later found her laying on her side. he picked her up and she went back into the lethargice stance. a bit later, i did see that she was walking around and had moved under a bench we have in the yard w/the other 3 birds. it appeared that they may have just been huddling because of rain - though we do have a covered run. i brought her inside to check vent - didn't appear to be plugged, though she had a lot of white sticky poo under her feathers. any suggestions as to how to proceed? have seen comments that it could be worm related? if so, any recommends on meds? at first i was chalking it up to going through and adj phase - i got her from someone at work who has about 25 chickens. i did ask him this morning if he had given us a sick chicken, but he insists he grabbed the first one that he could and i tend to believe him to be an honest person.
