My daughter gave me 10 chicks to raise for her and then she would pick out the best for her breeding program. They were born June 1st. Around July I had one get lethargic and I thought it was due to it being so dry and it got dehrdrated. I nursed it back to the point that it was walking and eating and never thought anything more about it. Then it came up missing. Now I have a hen acting the same way. She is wasting away. Her crop is empty, she is way down in weight but yet she stilll gets around good. Its just that she goes off by herself and sits. I don't see any lice. I just went to the barn and force some yogurt down her throat along with some chick feed that I had handy. I have about 20 or 30 chickens (including all the chicks) that are all free ranging. They have access to water in a stream at all times. No one else seems stressed or lethargic. She has layer mash available at all times and I feed 1 scoop of scratch to all of them. Her breathing is labored. She has her mouth open and is just huffing away. Any suggestions as what to try next? I hate to lose her as she was breed quality so far.
