Below is a post of mine I found that talks about weights, But if I remember correctly I didnt weigh them after they went out into the tractor. Not for a few weeks. I think 3 weeks -1.5 lbs, 4 weeks 2.5 lbs, 5 weeks -3.5-4 lbs, 6 weeks, 6 lbs, 7 weeks, 7.5-8 lbs, 8 weeks 9.5-10 lbs That would be my guess.
______Ok, here they are!... so they are almost 4 weeks old. (Ive had them 3 weeks 5 days). I weigh every Wednesday. Last Wednesday the average weight was 1 lb 12 oz. Biggest was 1 lb 14 oz, smallest was 1 lb 3 oz. So I'm guessing they are 2.5 now? I dont know if that's average, or small-- certainly a lot smaller than some!! We'll see on Wednesday. They forage like nuts when I move the tractor in the AM. I will start moving it twice a day next week. They are still feathering out, but its coming along. They are all males. In the background you can see the box I gave them to cuddle under. Seems to be working. Nights are about 5-7 degrees Celcius here.
It is shocking how much they eat. I feed them 8 am and 5 pm. They get any leftover scrambled eggs, or bits of fruit too, and a few oats here and there. And I give them a handful or two of turkey starter each day ..and about 20 scoops of organic feed.
I try and keep them full enough so that there isnt a crazy frenetic feeding frenzy, but so that their trough is empty by the time I feed them again. They are drinking about 1.5 gallons a day. There are 25 still!____________
I think I fed them a total of 1 bag of turkey starter 27% protein, mixed with all of their organic chick starter 22%, then i switched to grower 20% and the last organic grower I switched to was only 18% protein (it was $27 a bag rather than $43).
I bought another bag of turkey feed (grower this time) 25% protein. I will use it on all my chickens (egg and meat) once in a while, a little sprinkling. With all the free ranging I think they need a little extra boost when there arent many bugs out.
