It's been cold and rainy all day and these guys are 3 months old. (They are outside in a tarp covered coop with a light on them) My hubby feed them and he said they just went crazy eatting well now one acts weird like it cannot breath well and it's crop thing is hard...it's like it got too full we dug some food out of its mouth and tried to get it to drink....it tried to throw up but nothing came up! I brought it in the house and put it under a lamp in my house and it was chirping and making little noises ....is there anything I can do? These are very special chickens and I am really worried about the little guy! I cannot stand the thought of something happening to it!!!! Help please!!!
