so i got them in june and they were 3 months old supposedly. theres one that looks fully mature with large red comb and wattles underneath, the others are getting to that point. i havent had the most mature lay an egg yet or even seem like she would. the rooster is all over the 4 of them, as if they are sexually mature. im jsut worried about egg peritontitis or being egg bound. had a friend that had that problem awhile back with a couple hens. i feed them layer crumbles, scratch gain/corn combo. they have water readily available, oyster shells are in the coop in a dish. i mix DE light with their food, and its sprinkled on the run and coop floor bi monthly. they live in a 10x 30 run with a BA rooster, black star hen, RI red hen, buff orpington hen, and 3 silver laced wyandotte hens. the coop is rather large 8x8. just used for roosting and food. am i doing everything right and just being paranoid about them having egg peritonits or being egg bound?
