Within the past two days my flock of 7 week old have been allowed outside during the day. I am located in New Hampshire where the nights have been in the low 40's and the days are 60-64. One of my Australorps seems to be having some difficulty this evening - here is what she is doing 1) feathers all fluffed out as if she is cold 2) a bit of discharge came from her mouth when I went to pick her up - kind of sandy, greyish green stuff 3) stretching her neck off to the left and then stretching out and she just seems exhausted. I have them on a Poulin starter, fresh water daily - no treats except for what they are finding in the dirt and grass in their pen. I have her in the house tonight - with water and starter in a small kitty carrier. Please if anyone can tell me what this might be and what action I should take. Scrambled egg? Leave her quiet? Thanks in advance.
