I have 7 month old New Hampshire Red chicken and I was feeding her some bird seed and she started to almost choke. She kept sneezing and had her mouth opened and a couple minutes later I noticed her eyes started foaming. I wiped it off and tried giving her some water but she didn’t drink any, she kept like coughing/sneezing for a little bit now. Her eyes haven’t foamed any more but she seems a little off and she keeps coughing/sneezing. And help or tips with what is happening and what I should do would be gratefully appreciated!
