I had ordered 25 chicks from a hatchery and they are now 12 weeks old. One of the Marans seems to be having a problem the last few weeks. She started out limping about 3 weeks ago but seems to be getting better the last few days even running. She is smaller than the rest of the group and I had just thought that she may have been trampled. Yesterday I noticed her behind the coop and would not stand. Her legs are tucked under her and she is very alert and eats, drinks, poops normal. I brought her in for the rest of the day and last night. Checking her before going to bed was able to get her to stand but on for a few mins. She stood for a few mins again this morning so decided to take her back to the coop but have since brought her back to the house. I had these babies vaccinated and have never ordered from a hatchery before although have a chickens for about 4 years. Not too sure what to do at this point. Any help would be great.
