Things are going great here in Colorado as far as integration goes.
The littles don't fit thru the escapes anymore and the bigs can fit thru when I open them up so I took the fence down today. So far it's going alright. They are staying to their own ends pretty much and there is food and water on each end as before. The bigs go from one end to the other and when they move the littles go to the other end. The littles aren't as afraid as they used to be so that's good too. The bigs are becoming so accustomed to the littles that there is very little pecking and picking now. During the day they chase the littles occasionally but the littles come right back and continue whatever it was they were doing. The littles are showing more boldness at bedtime as well. There is still 1 RIR that "tries" to keep the littles out of the coop but they just slip in beside her and roost anyway.
The bigs have finally realized that they can't all fit on the top of the ladder roost so the 2 RIR's have started roosting on the bottom rung. The last 2 nights one of the littles has perched herself up there right between them big as you please. If there is a peck I pop them on the head and it quits. The little just sits there as if to say "Make my day". The other 2 littles are still using the side roost and all but 1 of the littles gets up all by themselves. The last one just wonders around the coop looking at the roosts as if she's thinking "Well how do I get up there?" I give her about 5 minutes to do this and then set her up on the side and shut things down.
The only issue I have now is that one of the Austrolorps started laying last week on Thursday and the first egg she laid was perfect. Then I got 2 small pullet sized eggs from her in as many days. The first 3 eggs were laid in a nest box. Then she started laying either no shelled or soft shelled eggs and dropping them from the roost. Two evenings ago I went out and she was hunched over with her tail folded down and looked in pain. I went to pick her up and she never let out a peep or tried to get away. This is one that doesn't like to be caught so I knew then she was not right. I lifted her tail and looked at her vent. It looked a little swollen and wet. I didn't know what to do so I just held and petted her for a while. She eventually got down and went to roost in the coop. About 30 minutes later the rest were in the coop roosting so I went to shut everything down and found a soft shelled and a no shelled egg in the sand underneath her. She looked very relieved and her vent was no longer swollen. Then today she laid another perfect egg. Not sure what to think... So far she is the only one laying. The bigs are 19 weeks old so I anticipate the others to start any time.
I mixed layer feed into the last of the flock raiser on Wednesday last week and they have oyster shell in a small pan attached to the coop support beam. I just filled it again last week so I know they are eating it. I have been giving them the left over pulp from my green juices as well as frozen veg popsicle treats when it's over 90*. It's been in the mid 90's for weeks and shows no sign of subsiding any time soon. Could it be the juice pulp maybe? There is lime pulp in it and I just read the "Chicken Treat Chart" that says not to feed them citrus but it doesn't say why. I did also do some reading here on BYC and several folks suggested a switch to bird seed without corn rather than cracked corn scratch in the summer due to overheating. I picked up some seed and a bag of just sunflower seeds. I mixed them together and added some oatmeal with it. They get about a cup in the mornings to share between all 10 of them. I spread it all over the 30' x 20' run to give them something to scratch at. Could this be what's causing the issue?
My plan moving forward is to stop the juice pulp and popsicle treats and maybe go back to regular scratch but only half a cup. If there are no more soft/no shell eggs then I'll know it's one of those things.
Learning never stops and I'm hoping that this takes care of the issue.
