hi our 2 year old hen is looking quite sick. she has lost a bit of weight i can feel some of her bones on her lower side. her comb is pale and shrunk. she now just lays down all day and doesn’t seem to get up and move. all of our chickens have stopped laying eggs due to the heat right now but the other three girls started laying about three days ago and she has not. last night she did not get up on the roost and just lied underneath the other girls which she has never done. i’m not sure what is wrong i kind of pushed her so i could see if something was up with her walk and she just flopped over. we put her in a kennel inside with AC, food and pedilyte. We have her a small dose of antibiotics left over from a previous chicken emergency that we gave her. also put a warm compress and valesline around her vent incase it was an egg related issue. i hand fed her some strawberries and she ate them very fast but won’t seem to eat on her own. About a week ago i noticed she was losing weight but thought it was due to heat. now i’m worries she is sick: any advice???
