Ok now I am really confused.Since this stuff is all new to us,Im not sure what to do.We have 3 black and 1 golden wyondottes.We were told the vaccines were in the feed.They were 1 year old on April 1st. All appear healthy,happy,eating n drinking.After going on the link abt eggs/shapes etc.There was a flat sided egg which we have had 2,there was funny grooves/wrinkles on the eggs posted and we have had a few of those(abt4-5) Our babies were all laying 1 egg a day counting the funky shped/flat ones and all those yolks n whites appeared normal.The golden stopped laying and her front waddles when she walks n looks like she has 2 big breast down in the front.Even though she ate,drank n seemed fine I thought she was just constipated n soaked safflower seeds in olive oil,fed her those n she pooped and layed a egg.she continues to go through spurts of no eggs n big front,when she lays the front goes down in size.Well the latest is even though we have had eggs every day,lately we were not getting any or just 1. one of them started laying a nice big/perfect egg up on the high shelf. I had written in before becuse I wasnt sure why all of a sudden they were not laying or they were eating em.Made a point of checking the coop every hr on Tues n had 1 egg on the shelf,1 in the nest and one on the floor the size of my thumb nail.Broke it open n the whites were normal n a speck of yolk. today only 1 on the shelf.They all seem fine,eat like crazy,drink and play.Is there anything I should do or look for? Isnt the vacine in the feed? My brother in law gave them to us n he was so proud of himself getting us tobe "chicken farmers" and he recently passed away.So these babies have a even more special meaning to us.Any advice.Thanks.
