Thanks for all the advise. They have plenty of ventilation maybe even aittle too much. The coop islarge and clean but may be too cold. I will slowly take off starter and give yogurt. I will do some changes to the coop too.
Thanks Nurse Turtle. I did take them off the medicated feed for one week then they all came up sick and my feed store told me to put them back on. I will remove them, as the bag is almost done now anyway. I will also add heat at night to take the cold edge off but I can't do more then that...
I got them in October and they were at least 5 or 6 weeks old. So I would say they are now about 5 months old. I have them on medicated chick starter feed still, as recommended by the feed store.
I purchased 20 chicks in October, knowing it is not the best time of the year to do so. They all survived chickhood, but since moving to coop in December I have lost 5 to unknown illness?? This first chicken I think had a broken leg and could not get to water and food enough. Seemed very weak...
