I have a chicken that didnt come off her roost yesterday morning which is unusual. Took her down put her outside with the others. She just stood there and eventually layed down even when they moved on. Checked her for an egg which i did feel one so i lubed her up and put her in the nesting box. Few hours later no more egg but still wasnt moving too much. Very alert though good color and eyes, good appetite and drinking. Brought her in last night but is the same this morning. Any ideas of what could be wrong? I wouldnt think anything was wrong with except the fact shes laying down a lot. Thanks guys!
