new to keeping chickens, so any guidedance or help would be gratefully received. got 4 hens from a rescue, they had come from ex-battery type place, they were sold as having their first moult so i guess about 14mo?? their feathers were a bit patchy, pale floppy combs, a bit sad and sorry for themselves. after 2 days one dropped dead, it had been hunched and closing is eyes and off its food in the morning and by the eve, she had gone. got given a re-placement for that one. that was about a month ago now, 2 of the hens combs now have colour, look good. the other 2 are not so good, one seems very light to pick up, her comb is terribly pale, feathers look dull, and dirty around back end, she is lame also. the other has an old injury to her wing that i spotted whilst checking her over, its on the 'elbow' a deep cut, that looks like it has been trying to heal for some time, im spraying that with a wound spray to stop any maggotts. this hen also still has a floppy comb with some colour and dirty feathers! they are all eating layer pellets, a few scraps here and there, they are free range. they rush up to me for food and wander about quite happy. so far i have wormed them, frontlined them (for the lice), loved them kept them clean and as happy as i can. i wondered if they has diarrheoa but from looking at the pictures or normal poop, they dont seem to...... the no eggs situation isnt really a concern for me, just want to do the right thing by them but what do people think?, if it doesnt sound very hopeful for them i would rather know now. thanks in advance.
