I have 3 pullets they are aprox. 28 weeks. I got them about 5-6 weeks ago. They were thin when I got them and since then I moved them into a much larger enclosure (from 7'x36" to 35' pen) less than a month ago they are now thin as rails. I know part of it could be that they now are getting exercise, but they are truly scary skinny suddenly. It was my intentions to worm this weekend but I'm afraid to now as they are starting to get weak. (As of last night one is showing signs, not as balanced and face is beginning to pale, egg is a bit thin) They are still alert and active but not eating much of their layers pellets (free choice in feeder) any more. I think they are now waiting for me to get home in the evening to free-range. They are stuffing their faces and going to bed with full crops of weeds, seed heads and bugs and such but still losing weight. I may have inadvertently created my own nightmare spoiling them to the point they have made themselves sick. :-( I need them to put on weight and FAST! Do I worm them this weekend knowing it could kill them? My kids would be devastated. Should I put the weight on them first? What can I use to do that? I have cracked corn - can or should I feed it free choice until they get some weight on and then worry about weaning them off it? Will it harm them besides perhaps not providing enough calcium and protein> I can give tuna or wet cat food (IF they will eat it) and mix in some crushed limestone. They used to go through a feeder of crumbles in 2 days. (small Little Giant feeder) Now a feeder of pellets lasts nearly a week. I think they are snubbing it, much to their own detriment. Whoever said they wouldn't starve themselves is wrong. I went to the feeding forum they said to try wetting the pellets, but I guess my girls are too picky for that, too. Can anyone help me?
