We are new chicken owners with 10 five week old Buff Orpingtons. They are still in a brooder (extra large dog crate in the mud room). They had been on medicated chick crumbles only, but read that chicks would enjoy treats of bugs now and then, which the kids have been giving them. We did not know that they would need grit if we gave them bugs. I feel awful (remember - we're new at this). 5 days ago one chick looked lethargic, wasn't eating or drinking, and her eyes looked dull. I made up another little crate for her to separate her from the others. She was barely pooping, what little bit that came out was watery and a little milky. After scouring the info on the boards I decided that maybe she had an impacted (impeded?) crop and, although it didn't feel enlarged, I began the olive oil and Poly Vi Sol treatments. I massaged her crop area several times a day. During this time she started drinking again and started to look a little better. Now I'm at a loss and I'm hoping someone can help. She is still sluggish. Still hasn't pooped, but is eating a little (crumbles) and drinking plenty of water. I have tried offering yogurt but she wants nothing to do with it. Her crate is next to the main brooder and when she has a little energy she will put her head through to try to reach the other chicks. I'll put her back with the others for short periods, but it seems to wear her out. Although she's slightly better, she is still a sick chicken, and I'm worried that she may not last much longer. We will do what we can for her here at home, but (please don't criticize) we do not want to take her to a vet or spend a great deal of money for treatment. We would appreciate any insight into what may be causing this and if there is something else we could be doing. I have read that some people use antibiotics, but wouldn't you need to get those from a vet? Thanks for any advice.
