I have 3 new EE hens from a swap Sunday before last. Since I got home 2 have been sneezing on and off and some snorting noises, mostly when I pick them up, I have them kept seperate from my flock, one of them has been laying but the other seems to be molting and has not layed. Both are eating layers pellets and drinking fine, poop is normal. The one that is molting seems less active . have given them some protein foods and I started them on vitamin water what should I do and could it just be stress.
