Thank you, they have clean water with vitamins and probiotic powder. They are eating chick starter and are all eating well. They are outside with the mommies with plenty of warm and cool spaces--our weather has been a little odd this time of year so we do plug in the heat lamp at night and if it is dipping before 55 at night. The coup has a closed hutch with shavings and and the outside is a large dirt yard--they have access to both food and water in the hutch and in the yard. The ones that are having difficulty walking rarely come out of the hutch. I do take them out a couple of times for a little while when it is sunny to allow them to bask, but do not leave them out because I am afraid they will not be able to get to the water or shade. They all started out great, very healthy, but within the past week they are all getting weak. Their poop looks normal, breathing is normal--it is just they seem like their little legs are not wanting to support them. The worst ones try to use their wings to help prop themselves up. Any ideas?
