So, of our two groups of new chicks the 3 12-13 week old Dominique pullets started with the sneezing and slight bubbles from noses. A few of the younger ones (4 week olds) had this off and on earlier this week and we attributed that to stress of the transition since it did seem to clear up. (We got them all Monday afternoon in an unexpected opportunity to start a much anticipated and dreamed of laying flock.) None seem to have anything worse than a case of sniffles so far. FYI for the younger ones (a group pullets of 4wks-7wks Speckled Sussex, Amberlink, and 2 Guinea Keets which may be pullets, hard to tell.) I have them on the ACV water (2Tbls per gallon), a little dairy kefir stirred into the bottom of the chick waterer and that seemed to help along with a better heat lamp. (They were kept inside until recently when they went out to a wooden brooder box on the front of our house to transition to cooler temps.) For the 3 month olds, I had them on the ACV water only and when they showed signs of sneezing I added a little kefir stirred in that. They are directly on the ground for 24hrs just now where they are currently at and before that they had a fresh layer of mulch on top of old mulch every 2 days or so until we cut the bottom out of the rabbit coop/cage someone gave us so we could start getting them used to being directly on pasture and moved them to fresh pasture. Dimensions are about 34 inches by 5ft. The sniffles started the day or so before we put them directly on the ground. They have a roost they sometimes use. Any further ideas? I'm thinking they need to be moved to new ground and we will probably do that soon here, but wondering if there are other ideas worth trying that we haven't yet? And if we need to be putting a heat lamp in there at night? (Regular bulb or red heat bulb?) The heat along with the ACV, kefir, time and of course prayer seemed to help the younger ones earlier in the week, but we haven't used heat lamps with these older ones at all so far and of course I want them to feather out prepped for cold and don't want to compromise that process. (Our neighbors have chicks the same age I think that are spending nights roosting outdoors by one of their house windows, by free choice. Those are different chicks of course, hence me seeking ideas.) For reference, we are in SW VA with warmer days in the 60's just lately (a little weird for this year) and nights warmer at 60' last night (really weird for this year) but usually in the low 50's, 40's or even 30's. The woman we bought these from said the 12 week olds didn't need a heat lamp so long as we wrapped the rabbit hutch cage with plastic, which we of course did right away upon their arrival, (3 sides plastic with cardboard flaps over the front window so we can open it up for them during the day and a bed sheet over that and the door at night to cut the wind etc.) My goal here is to strengthen their immune systems to do the work they are designed to do as much as possible since they will be exposed to things no matter what being out on pasture. Budget is super strained so trying to not have to spend more on medications too. This is our own personal egg laying flock we are starting and while I'd hate to lose any, I know things can happen, especially with new chicken keepers. We are trying to make the best of an unexpected, great opportunity to finally get this started. Ultimately we plan to keep them on pasture in a hoop coop that we are preparing to build in the next couple weeks (I hope.) Thank you in advance for your kind thoughts and ideas! This forum was highly recommended to me by a farmer friend of ours whose animal farming practices we admire and appreciate. Update: Now one of the younger speckeled sussex chicks is mouth breathing/gasping and sneezing. Because my husband and I are third shift right now, I was doing chicken care chores after sunset and might have allowed more cool air in there than she could tolerate. I refreshed their waterer while I was checking on them just now and pulled the plastic cover over their brooder box a bit better to keep more cold out and heat in to hopefully help her. Update again: She wasn't gasping or mouth breathing when last I checked on them. Seemed better. Hope this improvement continues.
