I have a silkie that is around 14 weeks old that is ill. Symptoms: Lethargic/weak Wings out to sides a little (hard to say if s/he is fluffed up - it is a silkie after all) eyes closed but will open them if you pick her up and talk to her. They are still clear. Crop had some food in it when we found him/her this way today but now it is empty Nose is clear seems a little on the cold side body tempature wise Poop looked a little liquidy/mucusy and was yellowish I have given her some vitamins and some sugar water. I also put the heat lamp on her for awhile but had to give it back to the baby chicks. She is inside the house so it's plenty warm. I did see her get up and stand for a little while and when I just went to check on her she moved her head towards the light. My hubby who went to bed later than me apparently "tucked" her in with a towel to keep her warm. None of the other chickens are acting ill at this point.
