I would appreciate some help. We have had three hens and just added five Welsummers to our flock. On first day together, two of my others pecked at them but now all seem integrated (day 5). One welsummer is suddenly listless, unable to stand, hold body up or raise head. Eyes are closed. Am I going to lose her? Any suggested remedies? I have just separated her from the flock and am trying to feed her warm water, milk and a little sugar. Introduced to new environment - none of my hens have had any ailments New hens have access to my other hen food - organic crumble Help please. Thanks.
