This site has been helpful the two times we have posted so here goes #3... We have an Easter Egger who is 4 mos. old and has been healthy up until today. We came home and let them out to "free range" for the evening and our son noticed Freita was wheezing when she breathes. My DH and I went out and sure enough she seems to be wheezing with some sneezing. We caught her and took a look at her. Her eyes, nose, comb everything looks as healthy as can be. We went to Youtube and typed in the search "wheezing chicken" and the first video that came up for us looks to be an EE with the EXACT breathing. We have all 14 chickens in a large outdoor pen during the day and in an enclosed chicken coop during the night. The coop has windows and an exhaust fan for ventilation. We have the windows cracked at night but not full open as it is getting down to the 40's here in N. Minnesota. The only thing that has changed is the introduction of straw on Saturday to the nesting boxes and the helpful chickens have spread it around the rest of the coop now! Seems to be clean straw, not wet, very dry with little dust it seems and no sign of mildew. Any thougths or ideas would be very, very much appreciated!
