Ok...so I am sure this has been asked, and covered ad nauseum, but bear with me ( I am new, first post). So, on Saturday, we got 10 baby BuffOrp chicks from our feed store (we've never had chicks before, but it was a planned purchase, lol). I asked how old, he said somewhere between 1-2 weeks. I think most were closer to 1, a couple are older (more feathered out, bigger). When purchased, they all had bright eyes, no pasty butt, alert, etc. None in the brooder at the store looked sick either. At home, we have them in our entry way (which the front door is never used and there is no heat vent right there to cause drafts. They are in a rubermaid type tube (like 3.5feet long, a foot and a half wide and 2 feet tall) on pine shavings with food and water. They have a chick feeder and one I made myslef so they all have access to it. Water is a one gallon one, that we add about 1/2 TBS of ACV to. The water is refilled daily and cleaned of shavings whenever I walk by and see shavings in it (at least 89billion/day, lol). We feed them starter/grower from Del's (20% protein) and add a tiny bit of chick grit becuase the guy at the store said there isn't any in there. They have two lamps, both 100 watt, that I raise and lower according to their behavior. They are handled daily and checked for pasty butts (none). They were all fine the first few days So, 3 nights ago, we lost one overnight. Didn't surprise me, sounds like some loss is normal. Then yesterday, one of the was really really lethargic, wouldn't stand etc. I seperated her into her own brooder, with a towel, a lamp, water, food. I syringe fed her some sugar water (which she drank) and wet some food crumbles (not really interested. I syringed her some more water after a couple hours, gave her a bit of yougurt (ate a bit when i dipped her beak in it), and dipped her beak in water a few times(she drank). She moved around a little bit(moved further from her lamp, so I raised it a bit). She did poo a couple times, but it wasn't bloody, not the height of normal (maybe shedding some intestinal lining, from looking at pics online). Anyhow, I am shocked she made it as long as she did. She was alive this am when hubby left for work, but not when I got up 3 hours later. Here's the rub, we also lost one last night before bed (pretty sure I bumped a lamp and it got too hot (finally put a thermometer in there and the spot she was was too hot. We lost one overnight (don't know what happened, hubby took care of it and I haven'y talked to him yet), and when I got up we had lost 2! Sick chick, which I expected, and another one. So we are down to 5! It's frustrating, because I don't know what is happening! Is it really because we didn't use medicated feed? We chose not to, with the idea that we prefer to not medicate "just because"...but with a 50% loss so far...I don't know. Maybe we should switch. And now I am a bit worried about having too few (heading into what is supposed to be a hard winter, for us) in the coop for them to keep warm, not to mention eggs for 2 families come spring... So, all that to ask, what the heck? Should we switch to medicated feed? Is there something we can give instead to help them be healthier? At about 2 weeks, should they be on paper towels instead? What do we do? I know some loss is to b expected, but half? Thanks all for your help...I don't want to lose more of these babies! ps, I know they are going to outgrow the brooder, so I am almost done building a huge one (2x6) UPDATE: So all 5 made it through the night. I left only the one light on, right under it is 95ish, and they do come right under the light at times, so I am leaving it at that temp for now. All seemed well this am, but now one of the smaller ones is having trouble walking/standing, and is getting more and more lethargic! What the heck is going on?!? I am going to the feed store tonight, to get electrolytes and organic feed...is there something else I should be doing? I know losing half isn't normal, and if this one goes too, it will be 6/10 that die! What am i doing wrong?
